Warbler Guy, which bird apps are the best to buy? There's a warbler app? Best bird app or best bird apps to buy?

Excellent idea, Joannie.

1. I suggest you purchase the fine wood-warbler-centric app that corresponds to The Warbler Guide:

It's found at the iTunes store or at the Google Plus store

Buying the book is also a good idea, if you wish a nice resource to complement the classic Warbler field guide in the Peterson Guide Series (Peterson Guide To Warblers, Jon Dunn & Kimball Garrett, 1997, Houghton Mifflin).

2. I also use:

iBird Pro

Sibley Birds

Both of these apps are EXCELLENT

I especially like the sonogram expression on the iBird Pro whereupon a song plays and I see the sonogram represented as the song progresses.

As for a GREAT Sibley Birds feature: the gull section is wonderful, given each age class phase (First Cycle through definitive plumage) is shown for each gull species.

So, for example, seeing the different age class phases/cycles of the Western Gull vs. the Glaucous-winged Gull is important because these two can hybridize and/or the 1st and 2nd cycle phases are sometimes challenging to distinguish in the field.

Sibley's app ALSO features different songs from various USA areas that are different song versions than those found in iBird Pro.....hence, both of these apps are complementary....and, as a result, I use each one often, especially on my bird tours that I regularly conduct for birders that hire me.

In other words, I like to let them listen to the songs of the bird species we are pursuing, especially if a birder is NOT familiar with the songs of the species we are seeking during a foray.

Regards and happy summer, Daniel
