Early Migrants Around Newton

Green Heron

 On my way to work yesterday I stopped off at Hammond Pond (checklist), Houghton Gardens, Lost Pond / Kennard Park, and finally Newton City Hall.  When I pulled into a parking spot at the overlook for Hammond Pond, a bird flushed from the grass by the inlet and I was surprised to see a Green Heron. (I later learned this is only the 2nd eBird record for Green Herons in MA this spring!) Usually I think of Green Herons as skittish and shy, but this bird only flew a few feet before landing. I hadn't even gotten out of the car yet and I was busy watching him with my binoculars. When he disappeared from view behind a bush. I slowly opened the door, and using the car for cover, crept around the side. There was no sign of a green heron, so I stopped being careful and approached the water's edge looking at for waterfowl. Just when I had forgotten about the heron, he leapt up from right in front of me, a testament to their camouflage, and landed in the adjacent bush. I immediately crouched and froze, starting a staring contest at a distance of 4 meters.

He eventually decided I wasn't interesting and began to use slow and calculating movement to make his way to the outer branches that overhung the water. I'd seen this look before, this was a master hunter on the prowl, creeping up on his prey. Eventually he was poised right above the water and leaning so far forward that I thought he must fall over.

Green Heron with Fish

At about this time, the Red-winged Blackbirds had taken notice of me and were scolding while Wood Ducks and Common Mergansers swam past. Then the familiar rattle of a Belted Kingfisher greeted my ears. I glanced up to observe the kingfisher flying towards me, catching sight of me, then turning back around to find another hunting perch, all the while giving her rattling cry.

Splash! I whipped my head around and the Green Heron was in the water. He had fallen in, as I feared he must, but wait - there was small fish clamped tightly in his bill! He made an awkward leap and returned to the branches, crest raised, to enjoy his meal. Now if only that darn kingfisher hadn't chosen that moment to fly by, I'd have seen the strike. But its hard not to look at a kingfisher. At this point the heron looked up and seemed to notice me as if for the first time and for posterity's sake, decided it was time to wander off into the grass surrounding the pond.

Ruby-crowned Kinglet

What a site to witness. But it was time to see what the rest of the pond had to offer. When I entered the woods, exuberant Ruby-crowned Kinglet song greeted me. Further along the trail I was pleased to find an Eastern Phoebe and my first warbler of the year with a bright yellow Palm Warbler. The high wheezy call notes of a Blue-gray Gnatcatcher guided my eyes to find several of these mini-mockers scattered through the woods. At the back of the woods I was lucky to see a Hairy Woodpecker chasing a Downy Woodpecker, it was great to compare them side-by-side and see how different their bill shapes are.

Back in Houghton Gardens (checklist), I found more of the usual, including another Blue-gray Gnatcatcher. I was hoping that a Pine Warbler might be gracing the gardens, but I did not hear any. I did manage to finally see a Ruby-crowned Kinglet though.

Next I headed over to Lost Pond and Kennard Park (checklist) hoping that the larger area of evergreens might hold a Pine Warbler. I really enjoy the Lost Pond area, though it isn't quite as bird-y as other Newton birding locations. This morning the pond held a few Mallards and a female Wood Duck. And while looking for ducks, this Ruby-crowned Kinglet started to sing near by and came even closer so that we had great views of each other (I was really excited to see that this picture turned out so well).

Pine Warbler

Further down the path there was another Gnatcatcher but once I got into the pines of Kennard Park I started to hear some musical trills. I thought to myself that it was likely a Pine Warbler, but I have a hard time identifying the trills by ear. It took some doing, but eventually I found a songster close to the trail and was able to follow his loud song back to a bright yellow Warbler. Finally a Pine Warbler. I sometimes have a hard time with Pine Warblers as they migrate on the early side, aren't as abundant in fall, and true to their name much prefer habitat with pine trees.

Then at the end of the day, I stopped by Newton City Hall (checklist) and picked up Chipping Sparrow, another Palm Warbler, and a Yellow-rumped Warbler. Now I had hit the trifecta of the common early Warbler migrants.

Fieldnotes from St. Louis

American Kestrel

 In March I had the opportunity to travel to St. Louis and the surrounding areas in Missouri and Illinois. Even though this area has many familiar birds, the relative abundance is quite different. As our Massachusetts farmland reverts to forest or is developed, grassland birds have been in decline. But the mid-west has lots of farm land, so these species are much more common. I had a blast seeing how common American Kestrels were in the area. As a kid, this was one of my most desired birds to see, so the chance to see and photograph them perching on wires right outside the hotel was fantastic.

American White Pelican

 One of the other great features of this area is the Mississippi River. Or more precisely the Mississippi flyway. Nearly forty percent of our waterfowl migrates along the Mississippi and Creve Coeur Lake had tons of ducks, including Canvasbacks and Lesser Scaups

Back at the river though, kettles of hundreds of American White Pelicans could be seen slowly wheeling their way north as they followed the river. I was lucky to have a couple of birds fishing on the river and afforded close views. Check out the horn on top of the bill that they grow during breading season.

Bald Eagle

Another major user of the river is of course the Bald Eagle. Its been a long time since I saw such a high concentration of Bald Eagles. I love watching them soar and those long straight wings are very distinctive.

One of my favorites experiences with Bald Eagles occurred on a canoeing trip. There were lots of eagles on the river, but at one point two eagles flew at each other, locked talons, and started plummeting towards the river. Just as they were about to reach the water, they broke apart and when their wings opened, the force of air on wing was so great it made a loud audible snap! And then they flew off. Later I learned that was part of their courtship ritual.

Okay I take it back, that wasn't one of my favorite experiences with Bald Eagles, it is one of my favorite experiences with the natural world.

Eurasian Tree Sparrow

I have to apologize for this bad picture of an introduced bird, but no talk of birding and the St. Louis area could be complete without the Eurasian Tree Sparrow. While I'm more partial to the American Tree Sparrow, the Eurasian Tree Sparrow is a close relative of the House Sparrow. But unlike its wide-spread relative, the Eurasian Tree sparrow is less aggressive and hasn't spread far from its site of introduction in St. Louis.

To me they also have a much friendlier appearance, or maybe I was just glad to add this bird to my life list.

Meadowlark

This next bird was a mystery for me. I just couldn't place it as an Eastern Meadowlark or a Western Meadowlark. There was a flock of 5-7 birds and heard a Western song from at least one member of the group, but what about the individual pictured? If you would like to guess don't read on as I discuss the results below.

My first line of thought was location. This area has a greater frequency of Eastern than Western Meadowlarks. Secondly, the song was Western, though the songster was likely a different individual. Then I looked at the malar (area behind the bill) and notice the limited yellow, Eastern birds have less yellow in this area. My forth clue was that the markings on the head have less contrast, more like a Western.

Meadowlark

Finally I looked to google and found this great page from Cornell Lab or Ornithology that compares field marks. This lead me to look at the barring on the tail feathers. Which looks Western.

To make sense of all of this I contacted some local birders who informed me that the thin barring on the tail is the best distinguishing visual feature and the song is really diagnostic. Additionally fresh plumages hide the yellow on the malar, so this feature doesn't appear until the feathers have worn off the buffy tips to reveal the yellow. That was a lot of work to learn that my ears didn't deceive me, this was indeed a less common Western Meadowlark!

I certainly learned a lot about Meadowlark identification, which I'll have to see if I can practice again soon.

A Birding Blitz: Newton and Beyond

During March 20-22, I ended up having a few days with the little one so the two of us set out on a birding blitz for the last day of winter and first two days of spring. Our rules were that our outings had to be entertaining and fit between naps and meals. So it ended up that most stops were about 30 minutes and I could only bring my binoculars. Sorry, no camera meant no pictures. But we had a blast.

As birding wasn't happening as heavily as usual I'll keep thing short and with highlights. Also this post is delayed as the Northern Pintail took precedence for posting. 

Crystal Lake (checklist)

While the lake was still frozen a pair of Canada Geese didn't mind as they grazed in someone's yard. I was excited to find a tree with 7-8 Fish Crows a couple of blocks away all giving their nasal calls. I didn't hear the tell-tale "na-uh" but they didn't make any classic American Crow calls either.
(Update from this morning: The lake is now open and hosting a raft of Common Mergansers, both American and Fish Crows were calling too. checklist)

Drumlin Farm

I thought at least I'd catch up with some Eastern Bluebirds here, but alas the bird life was non existant that afternoon. I did enjoy getting to see the hawks and owls in the exhibits up close though. And the newborn lambs were a big hit with the little one. 

Broadmoor Wildlife Sanctuary (checklist)

I'd never visited before and was excited to see how beautiful Broadmoor is. The highlights were Eastern Bluebirds (checking out nest boxes already) and a Winter Wren. It has been a long time since I've had the pleasure of viewing a Winter Wren. I'll definitely be coming back. 

Charles River by Commonwealth Ave. (checklist)

Highlights were definitely the diving ducks with Ring-necked Ducks, Common Mergansers, and Buffleheads. 

Hemlock Gorge

The only bird life was a faint call note that I couldn't make out, but that didn't detract from the natural beauty of Hemlock Gorge on my first visit. 

Lost Pond (checklist)

The pond was still frozen, but singing Juncos and House Finches were refreshing signs of spring. 

Hammond Pond (checklist)

I was very excited to see that the ice was finally breaking up! Seeing Canada Geese and a pair of Mute Swans in the open water on the far side gave me a ray of hope. Hammond Pond did not disappoint with Ring-necked Ducks, Common Mergansers, Mallards, and 6 Wood Ducks! The little one was so excited by the Ring-billed Gulls wheeling overhead or when the ducks would fly right past us. Just as we were leaving a Turkey Vulture teetered as he soared over the pond on his dihedral wigs. 

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).
