A Northern Pintail Drake at Chestnut Hill Reservoir

Northern Pintail

  After a a couple of days of a birding blitz (maybe that is for another post), I knew that the ice on the local ponds was breaking up and had been keeping an eye out on eBird. So when I saw that a Northern Pintail was seen at Chestnut Hill Reservoir over the past few days I decided to check it out on my way to work this morning. I was fortunate to find my life Northern Pintail as a female at Jamaica Pond back in January, so today I was really hoping for a drake.

Wood Duck

When I turned onto Chestnut Hill Dr. from Beacon, I saw large group of birds on a small patch of open water. My heart skipped a beat as I caught a fleeting glimpse of a drake Northern Pintail in the mix, that color pattern is quite distinctive! After parking I made my way back towards the West side of the reservoir I added Common Mergansers, Hooded Mergansers, and was surprised to see a female Wood Duck in a flock of Canada Geese. Additionally a Song Sparrow sure new it was spring from his non-stop singing (full checklist here).I saw a flock of ducks take off and was hoping the Pintail wasn't among them, but fortunately he was still in the same place and keeping company with a group of Mallards.

Northern Pintail Preening

I think that many of our local ducks are quite beautiful (Mallards, Green-winged Teals, Wood Ducks) but none of them holds a candle to a drake Northern Pintail in sheer elegance. The long and slender profile combined with the chocolate brown head with white accents and the textured back make him a pretty dapper sight. I kept thinking that he was dressed in him finest suit and there were no ladies to be impressed. Maybe he'll fine the female that over-wintered between Jamaica and Leveret Ponds. He even flashed his green speculum feathers while preening. I spent maybe 10-15 minutes watching him and taking pictures. Much of the time while I was there he was vocalizing with a soft trilled whistle, much sweeter than a Mallards harsh sounds. But honestly, what else would you expect from a duck dressed like that? He actually sounded similarly to the Eurasian Teal at Newton City Hall. I tried to take a video so as to share his vocalizations but I'm afraid its a little jittery as the post-processing stabilization didn't work at all! But I thought I'd still include it just for the vocalizations, which will probably require that you turn up for volume a fair amount.

Snowy Owl at Boston's Belle Isle Marsh

Snowy Owl

 Two winters ago (the 2011-2012 season) had a great influx of Snowy Owls, so back in December I was amazed to watch an even larger invasion of Snowy Owls occur this winter as reports from all over the state and the rest of the East Coast poured in, this was going to be one of the biggest Snowy Owl seasons recorded. I knew that I would have to go and find at least one of the owls, so when I saw reports on Massbird of reliable Snowy Owls at Belle Isle Marsh in Boston, I made my plans.

Red-tailed Hawk

My first visit at the beginning of February sadly turned up no owls, but I was pleasantly surprised to find a state first Eastern Meadowlark out in the marsh. I thought my eyes must be playing tricks on me, but apparently there were other recent sightings of the Meadowlark. This is one of the reasons I love birding at Belle Isle Marsh, it has some fantastic habitat and has given me the opportunity to find many birds without needing to tack on a long drive. Some of my favorites memories from past visits to Belle Isle include watching Least Terns diving into the salt pans, startling Bobolinks from the trails, and hearing Willets calling from the marsh.

But this winter, the landscape has been drastically altered into a snow and ice scene suitable to the far arctic reaches of this planet. Ice flows lay broken on the marsh as the tide repeatedly lifted and dropped them on higher ground. Only the banks of the channels and few tall marsh grasses escaped the blanket of snow. Fortunately Belle Isle's current resemblance to the arctic tundra has led to a Snowy Owl or two taking up residence this winter. With a total of three visits in February, last weekend was the charm as I finally caught up with this bird that so many people had been reporting.  As my friend Greg and I walked out to the boardwalk overlooking the marsh, I was able to spot something that looked suspiciously like a Snowy Owl before I even raised my binoculars. Greg works down the hall from me and we've been swapping stories about Snowy Owls since we met, so it was quite a pleasure to finally get a chance to find one together.

Belle Isle Marsh

We must have sat on the edge of the boardwalk in the chilly wind for 20 minutes just watching her rest in the sun. Her head swiveled around to take in her surrounding and would occasionally look directly at us with those huge yellow eyes before resuming her vigil. Snowy Owls can have quite a lot of variation in how much dark brown barring they have in their feathers. As the owls grow older they become whiter and male owl tend to be lighter than females, though there is much overlap in the amount of barring (I found a much whiter Snowy Owl at Duxbury Beach 2 winters ago). This owl from Belle Isle seems to be slightly on the darker side, but there are definitely still darker individuals.

Mute Swans

With difficulty we tore ourselves away from the Snowy to check out the rest of Bell Isle Marsh. Out in the water American Black Ducks, Mallard, and Buffleheads were evident. One of the coolest sightings were two sets of three Mute Swans that flew overhead. I momentarily got my hopes up for Tundra Swans, but they were still beautiful to watch as I've rarely seen them fly before. The rest of the bird life included some usual winter residents, though I also saw reports of plenty of raptors, Horned Larks, and Snowy Buntings.

After telling some of my other co-workers about the owl (who doesn't love a Snowy Owl?), I heard that one of my co-workers thought he saw a Snowy Owl at Newton Center Playground maybe about 8 years ago. Just when I thought we'd never find a Snow Owl in Newton, though it would probably still take some uncommon luck to repeat that feat. So I'll leave you with a link to the ABA Blog about crazy places that Snowy Owls have been found during this winters invasion.

A Hooded Merganser Study

I've always thought that Hooded Mergansers were one of the most beautiful birds to be found during the winter. They are usually way out on the water and are a little shy, so getting really good views or pictures of them is always challenging. I lucked out though on December 30th with two pairs of Hoodies in the Emerald Necklace in Boston. They didn't seem to much mind me, so I ducked behind some trees to take pictures and was treated to great views of them up close. I would always try to guess where they might resurface after a dive and was often quite surprised! (Click to enlarge the pictures)

2013 Recap and Recent Sightings and Thoughts

Mute Swans on the Charles River

 Since 2013 was the first full year of this blog I thought it would make sense to do a 2013 recap. A quick look through my eBird records for Greater Newton, which including immediately adjacent birding area (see here), give year count of 106 species while my Newton life total stands at 130 species.

I'll just list some of my favorites for the year:

Common Redpolls at Nahanton
Redheads at Hammond Pond
Tennessee Warbler at Houghton Gardens
Eurasian Green-winged Teal at Newton City Hall (and Bullough's Pond and Cold Spring Park)
 Yellow-breasted Chat, Philadelphia Vireo, Lincoln's Sparrow and Clay-colored Sparrow of Nahanton
Common Raven in Newton Center

Oddly I went the whole year without seeing any Ring-necked Ducks. Previously they were easy to find at Hammond Pond in the winter.

Red-tailed Hawk After the Hunt

Okay onto 2014. A few days ago I stopped by Millennium Park (the source of this posts pictures) after making a stop at Nahanton in search
 of the Northern Shrike. Part of my logic for visiting these places is that a Shrike was seen at Millennium back in Dec. They can have fairly large winter territories and prefer open spaces like fields and marshes. Given the sightings at Millennium and Nahanton this winter, it may not be too much of an assumption thinking that its territory may center on the Charles River and the wetlands at Cutler Park and surrounding areas.

But alas I did not find the Shrike. I did however get to watch as a Red-tailed Hawk launched himself off a telephone pole and swoop down into the fields and then return with a small mouse like critter. I then got to watch a lesson in mouse anatomy as the hawk ate lunch. The thing that surprised me the most was that he didn't seem to fall onto his prey that quickly, I almost thought he had decided to gently land and then spend time in the grass. It wasn't until he flew back to the light pole with prey in his talons that I knew for sure what had happened. Other than the excitement of witnessing the hunt from beginning to end, only some of the regular birds were around (full checklist here).

The Starry Sky on New Year's Eve

Jupiter in the Night Sky

 December was a busy month with the holidays and lots of things going on. I didn't get to bird very much and when I did there wasn't much to report so I was not inspired to post. Hopefully I'll do a recap some point soon with some pictures.  But I decided I needed to do something cool to end the year, even if it wasn't birding.

So I turned towards the night sky.

Having received two astronomy apps as gifts, my interest was piqued. I kept observing the stars. On a hike on Christmas Day while visiting family, I learned that the bright star in the west was indeed the Evening Star, or Venus, see the Nahanton Park blog for more on Venus. (As a birding tangent, my favorite bird of the day was a Belted Kingfisher.) The next night I went outside later in the evening and the brightest star I could see was actually Jupiter. I raised my binoculars and could make out a couple of pinpricks next to it: moons.

I have known for a few years that I could see the moons of Jupiter in my binoculars, but now with a new camera and lens, I was wondering if I could catch them in a photograph. On January 5th, Jupiter's and Earth's orbits will be at there closest, so New Year's Eve was going to be a great time to view the planet. And I was going to be awake anyway! So just before 10pm I bundled up, grabbed my camera and tripod, and headed into the back yard (an article on viewing Jupiter).

Jupiter and the Galilean Moons:
Ganymede, Io, Europa, and Callisto
(starting near Jupiter in order of increasing distance)

Finding Jupiter was the easy part. Getting my camera pointed at it and then finding good settings was the hard part. My fingers went numb. The image at the top is overexposed and uncropped to give a sense of relative size and position. The field of view is so small no major stars are visible, but some of Jupiter's moons can be seen. Also there is an interesting green streak that I'm going to try and figure out.

I kept trying and finally managed to capture a decent image. But what was most amazing was that I could find all 4 of the Galilean Moons. I could never hold my binoculars steady enough to see all of them before. The Galilean moons are the major moons of Jupiter and are named after Galileo Galilei, who may have first seen them, but was definitely the first person to realize that they were orbiting Jupiter, and not independent stars. This was the first time objects were observed orbiting a body that wasn't the Sun or Earth. This work was done 403 years ago this January.

The moons orbit Jupiter very quickly, with Io the fastest at 1.7 days and Callisto the slowest at 16.7 days. So every night the moons will be in different locations. (Here is a webpage that gives details on the locations of the moons in relationship to Jupiter.)

After having so much fun with Jupiter and its moons, I was curious what else I could point my camera at. So I chose to look for the Orion Nebula, which is located in the middle of the sword in the Orion Constellation. I'll end with this last image (centered on the Orion Nebula), but needless to say, I had a lot of fun on New Years Eve!

Searching for Newton's Eurasian Green-winged Teal

As I mentioned in the last post, there was an eBird report from Ryan M. from this past Monday indicating that a drake Eurasian Teal was found at Newton City Hall. Because Green-winged Teal (American) and Green-winged Teal (Eurasian) are clunky names for the purpose of writing, I'll just refer to the later as the Eurasian Teal (known as the Common Teal to the rest of the english speaking world). See the post from last year about the recurring Eurasian Teal for background, pictures, and discussion on identifying the different Green-winged Teals.

Hooded Merganser Pair at Newton City Hall

Ok enough with semantics. A Eurasian Teal was seen and I wanted to find it. So in between cooking yesterday, I went to Newton City Hall to go searching. I got excited when I saw a pair of Mallards and a pair of Hooded Mergansers (phone and binocular pic), but my spirits dropped as I slowly began to realize that there were no teals, nor did Bullough's Pond have any birds on the water in my quick glance. Fortunately, a pair of Golden-crowned Kinglets was quite entertaining to watch (full checklist here). I was starting to get really worried that the recent dredging had turned the marshy, weedy, birdy City Hall ponds into the poor habitat reflecting pools they were intended to be by Fredrick Olmsted (who also designed the Emerald Necklace). Green-winged Teals love marshy habitat that is now absent from City Hall and I was worried that we had improved away the Teals.

Hermit Thrush in Cold Spring Park

On my way home I even drove through Newton Cemetery to scan the ponds, but again just turned up Canada Geese, Mallards, and Hooded Mergansers.

I couldn't give up yet. So this morning I headed to Cold Spring Park and at 8:45 this morning it was quite cold. And so most of the ponds were frozen. I did manage to track down a flock of 12 Mallards in one of the streams, but no teals were to be found. I did hear a Brown Creeper and saw a Hermit Thrush, but interestingly, there was another thrush, that didn't have as much red on the tail as I was expecting. But given the time of year, that is the most likely option still (let me know if you have any ID thoughts and full checklist here)

After Cold Spring Park I just couldn't give up on the Eurasian Teal yet. With ice on the ponds, I thought that the ponds at Newton City Hall might just have enough current to keep them open. So I headed back there and was so disappointed when the grounds crew had leaf blowers cleaning up the park. No way any duck in their right mind would still be around. I walked up to one of the foot bridges and heard lots of junco call notes while movement on the water caught my eye. Ducks - teals - horizontal white stripe - Eurasian Teal! I couldn't tell if his lady friend was an American or Eurasian type, it might be possible to tell females apart, but it is still very challenging. I kept my eyes on the pair before a native Green-winged Teal drake joined them. They all headed to the farthest North pool nearer the leaf blowers before they disappeared. I don't think they flew off, so I wonder if they were hiding in the outflow culvert that leads to Bullough's Pond.

Green-winged Teal (Eurasian) at Newton City Hall

I was relieved to think that the pond dredging hadn't completely put off the Eurasian Teal, though I wonder if he will stick around the same amount without the marsh. And I am calling this The Eurasian Teal, because I'm increasingly convinced that all of the sightings within the area are probably the same individual. His primary haunt is Newton, and has been seen every Winter (Nov-March) since he was first sighted in Cold Spring Park in 2009. So this is the 5th consecutive year that there has been a Eurasian teal seen between Concord and Newton with only one year where he wasn't seen in Newton. But at no point in time have there been two Eurasian teal sightings on the same day at different locations. In fact there are times when he disappears from his usual Newton location for a few days and has a brief sighting elsewhere. Here is a quick list of eBird sightings for Eurasian Teals within at 15 mile radius.

2009 January. A Eurasian Teal sighted at Cold Spring Park.
2009 March 13. A sighting in Sudbury
2009 March 16 - April 4. Repeated sighting at Cold Spring Park. (There were also 5 days were he was absent in March which corresponds with a single sighting at Great Meadows NWR on March 25.) There was also an article in the Newton Tab about the bird.

2010 Jan-Feb: Repeated sightings at Newton City Hall
2010 March. Several sightings at Nine Acre Corner in Concord.

2011 March: Several sightings at Nine Acre Corner in Concord. If I remember this was a particularly harsh winter and all the local water was frozen, so its not too surprising that he wasn't seen in Newton or earlier in the year.

2012 Nov-Dec. Repeated sightings at Newton City Hall. (Again there was a stretch of time the bird was absent while a few sightings turned up on the Charles River by Norumbega Park which, if my memory serves, corresponded to a cold snap and ice on local ponds.)

2013 (so far) Nov. Two Newton City Hall sightings.

Green-winged Teals (European Drake and unknown female)
Newton City Hall

Now that I feel good saying that this is indeed the same individual, The Newton Eurasian Teal. I just looked up Green-winged Teal lifespan and see that 20 years is the average lifespan, so it is certainly possible that the Newton Teal could keep returning to us for a while. We will just have to keep looking for him. If he has any breeding success then we should also think about the possibility of hybrid Teals. Hopefully I'll get a chance to go see him again this winter and we'll be able to find him in the coming years.

Exotic Duck Chase: Mandarin Duck at Leverett Pond

Mandarin Duck

Last week on Massbird there was a flurry of posts about a Mandarin Duck drake that was spotted at Leverett Pond in Brookline. Mandarin Ducks hail from far Eastern Asia (including Japan, Korea, China, and Russia) and have never been known to grace our continent as a vagrant. Therefore the assumption is that all Mandarin Duck sightings are individuals that have escaped from captivity and indeed there are two known breeding populations in in the states ( North Carolina and California) that have been established from escaped birds. Sadly though their wild populations are greatly reduced as much of their habitat has been developed.

I have only seen two Mandarin Ducks before, and these birds were in Newton. A pair of Mandarin Ducks were actually housed in a gardening / landscape exhibit in the mall in the Winter of 2010-2011. While not wild, I was struck by how beautiful they are and how similar they are to our native Wood Ducks! The females are remarkably similar and then more and more I was able to see similarities the longer I observed the drake.

This initial encounter made me quite excited to have the chance to see a Mandarin Duck in a more realistic environment. Not to mention it had been observed in the company of a flock of more than 30 Wood Ducks, which would be a spectacle in and of itself. So, Monday morning with temperatures in the teens, I took the T to Brookline Village in search of this exotic duck.

When I arrived at the pond, much of the pond had a thin crust of ice. Fortunately the outflow was clear of ice and contained a large number of birds: Mallards, American Black Ducks, Canada Geese, a few Wood Ducks, even a Double-crested Cormorant, and a statuesque Great Blue Heron who tucked her head away trying to stay warm. A small knot of gulls were standing out on the ice, while Red-tailed Hawk flushed a flock of ducks from the center of the pond and they all circled off. I kept working around the pond and found the typical passerines in the trees and brush. Soon I ran into another birder who was saying she had just seen the Mandarin Duck but it just took off a few minutes ago and she pointed North. What luck. I wished I had been able to drag myself out into the cold a little earlier. As we were talking a flock of ducks landed on the pond and so glimmer of hope returned.

Raft of 36 Wood Ducks

I counted 36 Wood Ducks in the center of Leverett Pond but no hint of the Mandarin Duck showed itself. I took a few moments to enjoy the spectacle of the Wood Ducks and decided to head back down the Muddy River, the direction the Mandarin reportedly flew, on my way into the city.

I peered into every corner of the "river" as I kept walking and turned up Mallards, Canada Geese, Black Ducks, and 3 hooded Mergansers. Firmly in the Riverway section of the Muddy River I checked out an area where I had seen a Wood Duck in the past, but no luck. So I carried on to the foot bridge and peered around the corner, when the water exploded. Three ducks flushed flying away crying "jeet jeet jeet", but one of the ducks had a bright white face and pick bill, it was the Mandarin Duck! He had been hanging out with a pair of Wood Ducks. The two males circled off to the South leaving the jittery female still calling in the pool. Not very chivalrous.

Mandarin Duck with Wood Ducks

So I turned around walking South back to Leverett Pond and was finally able to see the Mandarin Duck where he was "supposed" to have been from the start. While he was further away, he also wasn't flying away allowing for great views. He truly was stunning. While the large white facial crescent, orange "beard", and raised orange feathers on his back that make up a "sail", he was much brighter than the Wood Ducks despite the similarities.

Walking in to work, I was then thinking about how long this Mandarin drake will be here with us. If he makes it to spring if he would pair up with a local Wood Duck. Though any crosses seem unlikely as Mandarin Ducks apparently have a different number of chromosomes despite the fact that Mandarin and Wood Ducks are the only species in the genus (Aix). Maybe he will stick with the local Wood Ducks and he'll be a local fixture for years to come, similar to the Eurasian Teal that frequents Newton in the winters (see last years post).

Speaking of the Green-winged Teal (Eurasian) that has spent the last few winters in Newton.... he is back! I just saw an ebird report from Newton City Hall. I am looking forward to going to find him again. Maybe that will be my next post...
