Warbler Guy, how do I know if warbler migration is strong? Migrating warblers are more dense on some spring days than other ones?

Fine question, Caren (in Austin).

I often use online radar to note spring migration trends.

One that is good: Birdcast



At this link, you'll read about the current week's presence of migrators and predictions.

It is a great resource, given the BirdCast forecast highlights migrant species that you can expect to see in each of several regions: Upper Midwest and Northeast; Gulf Coast and Southeast; Great Plains; and West.

Warbler Guy, what is the new warbler taxonomy? Why is the warbler family rearranged?

Those are great questions, Posey (in Seattle).

The best way for me to explain the answers is to point you to:


Here, you'll learn, for example, that the Parula, Wilsonia, and Dendroica genera have vanished, with their species merging into other genera.

There's also a link to a Q & A interview with Irby Lovette, who is the lead author and researcher that championed the taxonomy changes.

Warbler Guy, is The Warbler Guide any good? Do you think it's worth buying?

Anita (in Carbondale, IL): Full disclosure.....I received a copy of The Warbler Guide when it first appeared.

That written, I would have absolutely bought it, if necessary.

It is excellent.

Many review of this guide appear online, so I won't describe its virtues here.

But I will note the publisher recently creating some downloadable apps from the book that
may interest you at:


At this link, you'll find Quick Finder PDF or JPG files for quick ID of warblers. For example, one download PDF shows all the faces of warblers; another depicts all the warblers from a 45 degree view; another shows spring eastern warblers; and, yet another, portrays them in their fall plumages.

Hence, beyond the book, the publisher (Princeton University Press) continues to provide free extras at its web site, with the best link at:


As for my own recent warbler sleuthing, the spring on the West Coast has been fruitful so far.
March and early April arrivals of nesters in our area such as Hermit Warbler and Black-throated Gray Warbler have followed February appearances of returning nesters Wilson's Warbler and Orange-crowned Warbler.

Happy spring birding and warbler finding, Daniel
