Here are a few other hybrid warblers I've come across on the web or in
literature

-Black-&-White Warbler X  ? (Golden-winged or Chestnut-sided)
(see:
http://www.amazilia.net/images/Birds/NewWarblers/Hybrid_Warbler.htm )

-Black-throated Gray X Hermit Warbler
(from Rowher,S, C. Woood, & E. Birmingham. 2000. Condor 102:713-718)

-Townsend's X Hermit Warbler
(Pearson & Rowher. 2000. Behavioral Ecology Vol. 11 No. 1: 93-101)

-MacGillivray's X Mourning Warbler
(BNA account for Mourning warbler)

-Common Yellowthroat X Yellow Warbler
(see:  http://www.montereybay.com/creagrus/mysWarblerSep06.html )

-Parula X Magnolia (possible, but not confirmed)
(see Voice of New Jersey Audubon - 7/3/2003)


By the way, Mike Busam has a really good essay on the 'Birding in
Cincinnati' site about the Cincinnati Warbler.  It's definitely worth a
read.  You can find it here:

Enjoy!

OK, this has got me thinking... Hybrid Warblers. How many are there?



Brewster's  (Blue-wing X Golden-wing)

Lawrence's (Blue-wing X Golden-wing)

Sutton's (Parula X Yellow-throated)

Junkin's (Mourning X Kentucky)

"Nirschl"- Parulean (Cerulean X Parula)

Cincinnati (Kentucky X Blue-wing)



Are there any other Hybrid Warblers in N. America?



I wanted to know what they are looked like so I could tell them apart.
From the
links below and other searches I did on the above names I found pictures
or
drawings of mostly male birds.



What do the female hybrids look like? I presume there are some. Every
once in
awhile I will find a warbler that I presume is female, because the
coloration is
drabber. But, the field marks are not quite right for the females in my
field
guides. I wonder if maybe in all my years of birding I may have seen a
female
hybrid. But, without pictures or drawings of female hybrids how will I
ever
know. If anyone, knows of a source please let me know.

        With so much attention devoted to warblers these days, it might
be

worth reminding everyone of a growing miracle. An apparent hybrid

northern parula X cerulean warbler returned this spring to the same

Toledo spot for the *fourth* consecutive year.

        Rick Nirschl discovered this bird on 5/16/04; this year he
noticed it

on 4/24. Certainly it deserves the name some give it, "Nirschl's

warbler," and a debt is owed to Rick and Brian Zwiebel and others who

documented this phenomenon. More detail is in Rick's article in the Ohio

Cardinal (Vol 27 #4, pp 164-168) and in pages of the late-lamented

Birding News at

http://www.ohiobirds.org/news.php?News_ID=97

http://www.ohiobirds.org/news.php?News_ID=88

        Also interesting is news on a hybrid warbler discovered in New
York

last year (New York also had a "parulean" in 2004, by the way). DNA from

this bird was examined in a lab, and you can look at photos of this bird

to tweak out its parentage on your own, as well as peek at the answers

provided by the genetic material, at

http://www.allaboutbirds.org/mystery/  There are some interesting

remarks about DNA testing and about hybrid birds in general. Might be

fun to see if you can figure this bird out before looking at the answer.

        I imagine the survival of a hybrid warbler into its fifth year
is

pretty unusual. I also wonder if, having survived its perilous first

year, the chance that such a bird might live into subsequent years

increases, once it establishes and follows successful patterns (such as

returning to Toledo every year). Wouldn't an experienced bird, having

formed successful habits, be generally far more likely than others to

survive any given year? Interesting stuff... Oh, yeah--does anyone know

of an example of a hybrid wild bird producing offspring with a third

species??
