b) a shifting of the falcon and parrot orders to new positions on the check-list.
There's many other scientific name changes related to genera, but I won't bore you with those details, though they are present at the above web site link, if you wish to visit it.The one that I think is interesting for our NBB area — given the resident presence of our urbane House Finch and its close relative, the Purple Finch that also is a year-round resident in the NBB area — relates to how these two species(and the Cassin's Finch) are NO longer in the Carpodacus genus.....they are now separated from the Eurasian Rosefinches and these three finch species have beenplaced in the genus Haemorhous, which is name of an old finch genus.
So, if you're still following me, in a nutshell: It's hello Haemorhous and good-bye Carpodacus.

Victor (in Chicago), one wildlife management technique currently employed to help create suitable breeding habitat for the Golden-winged Warbler (and other species that, likewise, prefer young, pioneer, second-growth vegetational habitats) originates from funding provided by such groups as The Ruffed Grouse Society, Wildlife Management Institute, the National Fish and Wildlife Foundation, and the American Bird Conservancy.
Interested in promoting young forest management as a
means to ensure the Golden-winged Warbler maintains its current breeding range
in the upper Midwest, these groups have provided funds to public agencies
(e.g., Wisconsin Department of Natural Resources) (DNR) that have wildlife
biologists that, in turn, coordinate educational workshops for landowners
interested in conserving the presence of their local avifauna species (e.g.,
This kind of
effort goes beyond Wisconsin, as my readings tell me one or more of the
aforementioned groups is also helping fund other conservation efforts and
management plans that seek to preserve various bird species’ populations, such
as Ruffed Grouse that also often prefer to nest in similar habitat utilized by
As for my
luck in finding Golden-winged Warbler recently, a fleeting glimpse with a
transient in Door County a few weeks ago is a fine memory, thanks to my friend
and wildlife biologist Paul Regnier who first spotted a foraging male.
I say “lucky” because I never consider this species to be common or abundant. Traipsing through various Wisconsin warbler-watching locations through the years has always resulted in no more than five or 10 detections of this species annually.
A rare vagrant on the West Coast to the Pt. Reyes National Seashore
area also occurs, though I’m usually tardy chasing it, thereby swinging and
missing at the pitches I see on the local North Bay Birds listserv within the
Marin County (SF Bay Area) location where I live (Novato, a northern Marin Co.

Warbler Guy, which warbler may disperse &/or migrate by July? Which eastern warbler species is a likely West Coast vagrant?
Heather (in Seattle) one good candidate as an answer to your questions is the Tennessee Warbler (photo shown here).
In the USA's
East and Midwest where this species is typically seen, its early dispersal away
from natal/nesting areas is common. Many upper Midwest states have August banding records of Tennessee Warbler
individuals away from their nesting grounds.
But migration patterns may vary from one year to the next. That's because annual numbers for Tennessee Warbler often correlate with the the intensity of the summer season's spruce budworm output (that is a
cyclical phenomenon in the boreal forest habitat where many breed).
Heather, some females arrive on northern breeding
grounds in the spring already pregnant due to mating that occurs during daytime
layovers in migration. In non-breeding season habitat, Tennessee Warbler is
often seen eating nectar and fruit.
me, the autumn in northern California where I live includes spotting an
occasional Tennessee on a cloudy or foggy day amid small refuge patches of
non-native Monterey Cypress within a west Marin County national park, Point Reyes National Seashore. That's
because this species is one of the most typical vagrant eastern wood-warbler
species to appear in the West.

By contrast, in the spring, during my annual spring jaunt to the Midwest, I'm often sweating by noon while watching the same species in northern deciduous hardwood habitat. There, it’s a common transient through Door County, a northern Wisconsin environ that hosts 16 to 18 nesting warbler species as the farthest southern terminus expression of boreal forest in the lower 48 USA states.
