Although the landbird migration includes thrushes, vireos, flycatchers, tanagers grosbeaks and other groups, around here it's the warblers that are the main attraction for most birders. Most pass within a span of a few weeks, are brightly colored, bounce around in the tops of 80 foot trees while singing loud, persistent songs that take some practice to decipher- in a nutshell they are challenging, but rewarding.
Among the 20 or so "easy" species, Black-throated Blue Warbler is one of the real gems.
Male Black-throated Blue Warbler- blue back
Dark blue and black, with a gleaming white belly, they often venture down to eye level.
Black throat and sides
They sing a buzzy slurred, sometimes almost dreamy "zur zur zur zeeee!"
with a distinctive white spot along the lower edge of the wing.
Black and White Warbler is one of our most common. They are among a small group that stays and breeds in our area. They sound like a squeaky wheel- "Eesy eesy, eesy eesy".
Black and White Warbler- no explanation necessary!
Another common migrant which occasionally breeds in the area is Black-throated Green Warbler. There were several males in the area where I photographed this female, but my attention was diverted for a while by a much rarer and uncooperative Kentucky Warbler. Male Black-throated Greens sing a buzzy song that sort of sounds like Zoo zee zoozoo zee"- which obviously translates as "trees trees, murmurin' trees". OK, I know how that sounds, but it is surprisingly helpful!
Female Black-throated Green Warbler- the yellow face and black throat are more subdued than those shown by the male.
Chestnut-sided Warbler used to be easier to find around here, but breeding populations have decreased and migrants seem to have as well.
Chestnut-sideds tend to be eye-level birds. The classic song goes kind of like "Pleased, pleased, pleased to Meetcha" with an emphatic ending. I can usually pick it out, but it is often very similar to Magnolia, Redstart and Yellow- all of which are much more common.
Dark reddish sides and bright yellow cap
A great looking bird- a lot of people's favorite!
And speaking of Magnolia, here's a poor photo of a nice male- one of my favorite birds.
This weekend's flight included a LOT of Northern Parulas-
Male Northern Parula
Parulas mostly stay up in the treetops, singing a rising buzzy song that goes up in steps, then 'flips' at the top. Very distinctive.

The only North American Warbler with a bicolored bill- dark upper and yellow lower mandibles.
and bold white wingbars.
There were a few American Redstarts in this weekend's flight, but they usually become pretty abundant by mid-May.

Lots of Wood Thrushes and Veeries were around this weekend as well. Of the six species of brown thrushes found here, Veeries are the least spotted on the breast.
Veery- not a warbler, but a thrush. Tawny brown above with almost no throat spotting.
Northern Waterthrush- actually a warbler, is common throughout the migration period. Its more southern counterpart, Louisiana Waterthrush, shows up here earlier- arriving in late March and barely lingering into May.
Northern Waterthrush- not a thrush, but a warbler..
Heavily streaked underparts including the throat- a characteristic that separates it from the similar Louisiana Waterthrush.
Another view of Veery.
All tallied- a total of 21 species of warblers at Alley Saturday morning. Not a bad start to the migration frenzy.
