Stork nests

watch your fingers

We made our annual trip to Florida to visit friends in Palm Beach County at the beginning of March. This is the latest in winter we've gone, and the differences in what birds were around were interesting.

domestic bliss

At Wakodahatchee Wetlands park, the Wood Storks were nesting. Some of them were in trees right next to the boardwalk, practically close enough to touch if you didn't mind losing a couple of fingers. In January and February of past years, the dominant nesters were Great Blue Herons; this time it was the storks and smaller shorebirds like Tricolored Heron and Cattle Egret.

All the little hammocks had nests in them. They were like shorebird condos. They generally had Great Blue Herons at the top.

"I just adore a penthouse view..."

Stork nests were below the Great Blues, and then Anhinga nests farther down.

nice neighbors

Cattle Egret and Tricolored Herons tucked their nests into cozy little crannies throughout the trees. Double-Crested Cormorants mostly had their own hammocks.

There wasn't much nesting at nearby Green Cay, though there were a nice pair of Screech Owl. The Spoonbills seem to have abandoned it this year, though. I'll post more Florida photos soon, in the meantime, one more Stork nest:

Spring is over, but summer hasn't started

Let's start with the big news from Central Park: the Warbling Vireos have hatched!

Warbling Vireo feeding nestling

The hatching happened over the weekend while I was sick, but I was able to get a couple of nice photos of the nestlings being fed today. I'm pretty sure there are at least two nestlings, and this species usually lays four eggs, so they might be more.

It was interesting watching the nest. It seems to work just as I've read: most of the feeding is done by the female, though the male does some and is always nearby guarding the area. What happens is, he'll give a short burst of song, then fly in to quickly check the nest, and fly off; sometimes he'll sing again after flying out. The female arrives a minute or so later and does a more thorough job of feeding.

Also, the intervals between feedings are surprisingly long (again, just as I've read), between five and ten minutes. They're supposed to get increasingly frequent during the two weeks it will take the little ones to fledge.

That seems backwards, doesn't it? Shouldn't the newborns demand constant feeding? I wonder if it's a defense against parasitism. The much larger cowbird babies need more feeding. That's why they kick their host's offspring out of the nest--they'd starve if they had to share resources at all--and kicking them out is part of why they have to be larger at hatching. Anyway, it seems to me that the very slow feeding schedule of the Warbling Vireos would be bad for such nestlings--maybe that's enough to keep their nests from being parasitized.

Anyway, Spring ended with the traditional sighting of a flurry of female Blackpoll warblers.

that's all, folks!

Blackpolls are the latest Spring migrants among warblers, and the females (as in many species) migrate later than males, so when you see female Blackpolls coming through, it's about over.

Of course, there are some later-arriving non-warbler species, like this Yellow-Billed Cuckoo.

a two-cuckoo year!

That sighting game me both Cuckoo species for the year, which doesn't always happen. And there are always stragglers, like this Lincoln's Sparrow who is stuck in Bryant park:

Lincoln's lurking near the library

There was a nice Swamp Sparrow, too, and a couple of White-Throateds, all around the birdbath in the northeast part of the park. Hopefully the'll all find their way out soon.

So spring is gone, but it doesn't feel much like Summer yet--cool though humid. But there are fledling birds all over--robins and Starlings and House sparrows, and at Turtle Pond, a raft of ducklings.

a raft of ducklings

I think these are Mallards, but another observer thought Gadwalls. There is a possibly nesting Gadwall pair as well as a female Mallard nesting near the pond. I think their bills are too long for Gadwalls, though those flank spots are very Gadwallish.

Since we're back to the baby birds, here's another pic of the Vireos. Wonderful little birds.

I warn you, you're going to be seeing a lot of this nest the nest couple of weeks

Prattsville: Bobolinks and Blackbirds

dig that crazy-looking bird

The bird I was most excited to see was the Bobolink. I'd never seen fany before, and when very early on Sunday morning I saw a blackbird with yellow on the back of its head perched on a power wire over a hayfield at a crossroads, I couldn't work out what it was. I watched it drop down into the tall grass, then pop back up on the wire. Its only vocalization was a guttural chuck, not as metallic as a Red-Winged Blackbird.

I riffled through my field guide, ruling out a vagrant Yellow-Headed Blackbird--and somehow missing the illustration of the Bobolink; I amaze myself sometimes, I really do. I was convincing myself that it was a red-winged having a really weird molt when another showed up. They both went into the grass, but minutes later, three more flew up from a field across the road.

OK, so not just a single bird having a weird molt

It wasn't until I got back to the house and sat down with the field guide that I spotted the Bobolink picture. Oh!

I hope those fields aren't mowed until the fledglings are ready to fly out (end of July). Earlier mowing would be a disaster for the Bobolinks. I saw those fields on Labor Day weekend last year and there were round bales still sitting in those fields and the grass looked like only a few weeks' growth, so maybe it will turn out all right. Here's an interesting article from the Audubon Society about the problems Bobolinks have nesting these days. (Unfortunately, the Bobolink Project website is down now; it looks like it had a lot of good information. Update 6/30/2014 - the site is back up.)

One of the other two corners of the crossroads had a field that was closely mowed, and the last was also in tall grass, but wholly occupied by Red-Winged Blackbirds.

The funny thing was, I was out for a walk on Saturday afternoon, and I didn't see any Bobolinks, only the Red-Wingeds. One male was posted a a sentry on a power line. He was giving repeated metallic chack calls, until I got within twenty yards, when he started giving high pitched calls and shuffling back and forth down the wire.

he didn't like me one little bit

Once every minute or so, he'd fly off the wire and circle about 10-12 feet over my head, then return.

I think the Red-Winged young must be fairly well along, since I saw a few females coming out. Around here, at least, that doesn't happen until they're near fledging.

Mama needs a break

Prattsville trip, part one

We had a lovely weekend at our friend's place in Prattsville NY. I was up before 6am each day, which has left me needing a rest, but was quite fun.

The meadow in front of the house was full of singing Common Yellowthroats and Chipping Sparrows. There were quite a number of Chestnut-sided Warblers as well, and in the trees at the east end of the meadow was this singing Prairie Warbler.

Sing it, baby!

I'll have more to say about the trip when I've caught up on my sleep--there were Bobolinks!--but for now I'll leave you with this pleasant scene of a Tree Swallow feeding its nestling.

Awwwwww

That nest box was in nearby Hobart, home of a half-dozen nice used bookstores.

It's a hard life being a bird

It's a hard life, being a bird. On Saturday came the news that the Ruby-Throated Hummingbird nest near Oak Bridge had been raided and destroyed by a Baltimore Oriole.

Photographer Roman Brewka was there when it happened and photos are on his website at birdsofnewyork.com in the "Recent Photos" gallery. They may be a little disturbing (or I may be too tender-hearted towards small birds), but he's an excellent photographer and you should check out his other galleries at least.

On a cheerier note, the latest set of Pale Male's offspring has fledged and today the area around the Toy Boat Pond was full of the cries of the young Red-Tailed Hawks. One remained perched in one place, taking a lively interest in passing small dogs.

don't let your dog run off-leash, OK?

One of his siblings flew in and rested in the grass awhile.

hawks on the grass, alas

People passed by; some noticed, some didn't.

just another New Yorker

The third was calling frequently somewhere to the north, but eventually flew into another nearby tree.

this must be the place

I say this was "cheerier", but the squirrels, and especially the Grackles, didn't really agree. The Grackles especially were very unhappy about the hawks hanging around their nesting area.

In the Ramble, things were quiet. A strange thing happened while I watched this fledgling Blue Jay.

they grow up so fast

Once in a while an adult jay would come by and smack the youngster on the head. Is this parental affection among Blue Jays? Was the young bird too close to someone else's nest? It wasn't a mobbing--the adults weren't hanging around to harass the youngster, just coming around every couple of minutes, peck, off again.

Nesting season

The flow of migrants has pretty much dried up, and the resident nesting birds are dominating Central Park. The first broods of Robins fledged a couple of weeks back, and many nests are still active. Starlings, Grackles, and House Sparrows are tending their first crops of fledglings as well. Cardinals are nesting all over, and so are various woodpeckers. A number of Warbling Vireos and at least two Red-Eyed Vireos are singing in and near the Ramble, so presumably are nesting, as are Eastern Kingbirds at the Upper Lobe at least.

And then there's this:

A Ruby-Throated Hummingbird, on a nest near the Upper Lobe. They don't usually nest in Central Park. I'm trying to fid out if that's ever happened before, in fact.

That nest is about the size of an espresso cup. It's made largely of spiderwebs and a bit of plant material. Usually there's some lichen stuck on the outside--I'm not sure this one is finished yet.

The next few weeks will be interesting.

Favorable winds

Gentle southerly winds overnight brought a few new species into Central Park on Tuesday morning. The big news was a male Cerulean Warbler spotted by Miriam (whose last name I don't know) at the Gill just south of Azalea Pond about 11:30am.  She was sitting on a bench watching birds coem down to bathe, and a Cerulean came down to eye level.

Unfortunately, only a couple of other people got to see the bird before he went back up into the treetops, as a Cerulean does.  I wasn't one of the lucky ones.  I found out about the bird when I got to the Azalea Pond around noon, and stayed  in the area for an hour and a half.  As far as I know, nobody saw the bird again.

Also reported were a pair of Purple Finches and a Northern Waterthrush, but I didn't see them either. Also a Savannah Sparrow at Maintenance meadow--this one I did get:

a very confiding Savannah Sparrow

A very cooperative bird. A group of birders stood off about 25 feet or so, not wanting to disturb it as it went about its lawful sparrow business foraging in the grass. It gradually worked its way closer until it was about 10 or 12 feet away. This is by far the best look I've ever gotten at a Savannah. Charming little bird.

In addition to the new species, a lot of birds from already-present species came in overnight. There were quite a few Yellow-Rumped Warblers (which I saw while looking for the Cerulean), Palm and Pine Warblers, a Blue-headed Vireo, and a number of Hermit Thrush. I did see a warbler, high up, a dull yellow breast with dark streaks; maybe a female Yellow Warbler, but not a good enough view to say for sure.

Most of the recently-seen species were still around, even if not in greater numbers.

Remember how I said in the last post that I didn't have any good photos of House Wrens? That's fixed now:

House Wren in action

While migration is just getting into swing, some resident birds have gotten down to the business of nesting:

Spring!
