Warbler Guy, can you name a common wood-warbler that migrates early in summer throughout the USA?


If you said “Yellow Warbler,” then you’re correct.

Rather than merely identifying this species as among the earliest “fall migrants” within the wood-warbler family, it’s apt to state the Yellow Warbler is an early “summer migrant.”

Dispersal and/or migration begins by mid- to late July throughout the majority of its eastern USA breeding range.

Migration of Yellow Warbler on the West Coast is not as early, typically initiating in August and peaking later in the month and into early September.

In addition, note this species has protracted migration, as some tardy individuals have been noted in Pennsylvania as late as October 1st and into late October from sightings in South Carolina and Florida.

Earliest arriving transients from the north into Mexico have been detected by late July. Most individuals, however, arrive in non-breeding territory by August, with peak numbers returning in September and October.

Warbler Guy, how do I know if my California bird sightings are rare ones? Are species of special concern in California present in a book?

Sherry, feel free to see:


Here, you'll see the publication whose cover is shown below. 

It's an excellent resource to read analysis of the status of California's at-risk birds using the latest data to describe current populations, ranges, and threats. 

Species highlighted in this 450-page book include seabirds, raptors, shorebirds, waterfowl, and perching birds, all of which are represented on a Bird Species of Special Concern list.

This list also notes California habitats with high numbers of special concern bird species, including wetlands, scrublands, grasslands, and riparian forests.

Traveling soon to Wisconsin, Warbler Guy....so where do I look up recent warbler sightings? Warbler sightings in Wisconsin are posted on ebird?

"Yes" to your question, Theo (in Chicago).

You would do well to see:


Then type in the warbler species you'd like to pursue in Wisconsin.

This link shows the latest survey results from WI Breeding Bird Atlas volunteers documenting
nesting bird species throughout the state.

For example, I recently visited WI to pursue Connecticut Warbler.

The ONLY documented sighting I noticed in n. WI is linked from a 5/24/15 observation at:


Let me know if I can further help.

Regards, Daniel

Warbler Guy, I'm traveling to Maine, so how do I find out about warbler sightings in Maine? Warbler sightings in New England?

There's a great web site operated by Steve Holzman (Thanks, Steve!) that I recommend, Betsy:


Here, you can see any state listserv with recent documentations of bird species, including wood-warbler species.

Paul Garrity operates the Maine listserv, which is at:


His "Media Shelf" link features excellent wood-warbler resources. See:



This post is brief because it's time to go prowling for owls tonight...in addition enjoy BRIGHT
Mars, which is at a magnitude of -2, so four times as bright as a "0" designation.

Enjoy the spring everyone, Daniel

Warbler Guy, tell me if migrating Kirtland's Warbler have returned to breeding grounds? Kirtland's Warbler migration in spring originates from where?

Jasper (in S. Carolina), given Kirtland's Warbler typically annually nests ONLY in Michigan and Wisconsin in the USA (and in one spot within Ontario, Canada), here's where I check this month to note when this federally endangered species has returned:

1. http://www.michigan.gov/dnr/0,4570,7-153-10366_54559_10402-357409--RSS,00.html

The contact you may wish to query:

Keith Kintigh, 989-619-2296

2. Wisconsin's web site (via its DNR) does not post updates of detected Kirtland's Warbler for the current nesting season, so the best way is to watch its birding listserv updates via the "Wis Birds List Serv" -- a term you should Google to subscribe.

Then you'll be able to see the sightings of birders who post.

3. As for Ontario, I'm not aware anyone or any agency provides information for this area's potential Kirtland Warbler nesters.

Meanwhile, have I heard about Kirtland's returning yet this May? -- based on the typical pattern of arriving around this date annually in Wisconsin (e.g., Adams County appears to sustain an annual nesting population of Kirtland's Warbler within Jack Pine stands.)

No...but I'm checking the Rare Bird Alerts, including #2, above.

I'll post here again this breeding season, if and when I hear about Kirtland's sightings in the above locations.

Happy Birding to all, Daniel

Warbler Guy, I'm traveling in search of warblers this spring: Where do I find warbler sightings online? Warbler observations are present at one web site? Rare Bird Alerts post warbler sightings?

Yes, Harold:

There's a one-stop shop for all your warbler watching needs at:


Look by region on the home page menu for the area to which you are traveling.

So, for example, at the above web link, pretend you're traveling to Michigan this spring.

Your aim is to find the Kirkland's Warbler that typically nests among 10 north-northcentral Michigan counties.

Look for this area on the web link and go through the dates to check potential recent sightings.

Easy, correct?

At Warbler Watch, we aim to please.

The birder customer is always correct.

Regards, Daniel

Warbler Guy, are any new "splits" or "lumps" of species proposed for birds this year? Will the annual American Ornithologists' Union name changes happen soon?

Norm (in Manhattan):

GREAT question and the best answer for Warbler-Philes is an easy one: No wood-warbler family (Parulidae) changes proposed, BUT (drum roll for Corvid and Fringillid fans):

- "Woodhouse" Western Scrub-Jay subspecies could be elevated to species rank, per a current proposal; and

- Lump of Common and Hoary Redpoll is also in the proposal stage.

That's your "elevator" pitch summary, if you wish the simple answer.

There's more details for other taxa/proposals, below....and ALSO at the following link:
