Warbler Guy, what about the Peterson Guide To Birds app? How is this app good for warblers? Other bird species?

Gloria, I've pasted a couple of excellent screen shots below for you to see how this amazing app features wonderful color plate drawings.

The warbler ones are equally impressive (though I did not share any here).

Plus, there's oodles of features on this app to use in the field and among your friends (if you all get it) that lead me to provide an "A" grade for this app.

Yes, I have it...and, yes, it was given to me (full disclosure!), but I'd also buy it, if necessary, at the iTunes Store.

Thumbs up from me.

To find it.....

Type in at the iTunes Store:

Warbler Guy, I know you're into the little birds, but you seem to live near recent Blue-Footed Booby observations in Marin County, correct? Have you seen the booby at Gull Rock like I read about on Rare Bird Alerts?

Yes, Germaine (in Seattle): I have led some bird tours there recently and, indeed, here's a photo from Isaac Sanchez on 11/5/13 when I served as his guide for the day.

Every time I've been to Gull Rock, one or two immature/sub-adult Blue-footed have been present FAR AWAY.

Thus, this photo is obviously a booby, but it's from at least .5 mile away.

Hope this helps you. Regards, Daniel

Warbler Guy, how many Kirtland's Warbler individuals hatched this year? Do Kirtland's Warblers face extinction?

Roy, in Racine, WI, here's a "copy & paste" from a fine email newsletter published by Wayne Peterson & Paul Baicich (via:, noting the 2013 breeding success of Kirtland's Warbler in Michigan, Wisconsin & Ontario:

(Before you read it, did you know Kirtland's Warbler has nested in Wisconsin for seven consecutive breeding seasons? More about the federally endangered Kirtland's Warbler in WI can be read at the WI DNR link provided on the last lines, below.)

The numbers from the last breeding season are officially in, and Kirtland's Warblers remain near an all-time high.

The Kirtland's Warbler survey is annually conducted by the U.S. Fish and Wildlife Service, U.S. Forest Service, Michigan DNR, Michigan Department of Military and Veterans Affairs, Michigan Audubon Society, and numerous citizen volunteers. Kirtland's Warblers nest on the ground in central Michigan, various counties in Wisconsin, and in Ontario where they usually select nesting sites in stands of jack pine between four and 20 years old. Surveyors seek out singing males on territory to identify this species during the breeding season.

Biologists, researchers and volunteers observed 2,004 singing males in Michigan during the official 2013 nesting survey period. An additional 21 singing males were found outside Michigan, in Wisconsin (18) and in Ontario (3).

In 2012, there were 2,063 singing males counted in Michigan. These numbers are in stark contrast to those of 1974 and 1987, when only 167 singing males were found - the lowest survey numbers ever recorded.

The current revival has been so impressive that removing the species from the federal Endangered Species list is a possibility, perhaps some time in the near future.

"Two thousand pairs of birds is still a pretty low number," warned Philip Huber, a U.S. Forest Service biologist working on the project. Because Kirtland's Warblers are so uniquely adapted to a sandy-soil jack-pine habitat, they now depend heavily on human intervention for survival (e.g., cowbird removal, pine-plantings, and fire-management).

"Our success is allowing managers to work with additional partners to transition from a mode of recovery to one of long-term sustainability," said Dan Kennedy, Michigan's DNR endangered species coordinator.
