This is the Voice of the Naturalist, a service of the Audubon Naturalist Society. This report covers the week starting Tuesday, April 26, and was completed on May 3 at 2:00 p.m.
Top birds this week are YELLOW RAIL* in MD and RUFF in DE.
Other birds of interest include TRUMPETER SWAN, loons, EARED GREBE, bitterns, YELLOW-CROWNED NIGHT-HERON, raptors, rails, shorebirds including PIPING PLOVER and RED KNOT, gulls, terns, BLACK-BILLED CUCKOO, BARN OWL, COMMON NIGHTHAWK, CHUCK-WILL'S-WIDOW, PEREGRINE FALCON, LEAST FLYCATCHER, COMMON RAVEN, vireos, swallows, SEDGE and MARSH WRENS, warblers including GOLDEN-WINGED and MOURNING, sparrows, SUMMER TANAGER, grosbeaks, and BOBOLINKS.
Overall, migration was in full swing.
A YELLOW RAIL* was found in Baltimore City, MD, by volunteers for Lights Out Baltimore! on the morning of April 27. This was the city's first confirmed YELLOW RAIL--and the first possible since 1893. The bird, which had struck a building during migration, was taken to a rehab center where it was examined, weighed, fed, and, on April 29, released on private property north of the city.
A REEVE—a female RUFF—that was first seen at Bombay Hook NWR, Kent Co, DE, last week proved hard to find among the hundreds of shorebirds milling about in Raymond Pool, but was reported again in the late afternoon of April 30.

This week's report was based on reports on the DE, MD, VA, and WV list servers via the ABA Internet links, and on eBird records.
The Audubon Sanctuary Shop (301-652-3606, http://anshome.org/shop)is an excellent source for guidebooks and many other nature-related titles.
To report bird sightings, e-mail your report to email@example.com. Please post reports before midnight Monday, identify the county as well as the state, and include your name and a Tuesday morning contact, e-mail or phone.
Thank you for your interest, and enjoy the birds.
*Of interest to the records committee.
The Voice of the Naturalist is written and recorded on Tuesday mornings. If you email your reports, please email firstname.lastname@example.org, by Monday midnight to make sure they are received in time.
Reports prior to the preceding Tuesday will not be considered.
The area covered is (with rare exceptions) DC, MD, VA, and southern DE; all other reports should be sent to the appropriate rare-bird alert for the area in which the birds were observed.
Be sure to report only those birds that you actually saw, not ones that someone else told you about.
And please remember to include a phone number where you can be reached on Tuesday morning; if you can't be reached to verify a rare bird, your report will almost certainly not be used.
There are two main circumstances in which a bird sighting will not be reported on the Voice as a matter of policy. The first is if the report would jeopardize the bird's welfare:
Reports of species that are threatened or endangered at the state or federal level are generally not used, especially during nesting season--local Loggerhead Shrikes are an example; similarly, owls are not listed, with two exceptions--Snowy Owl and Short-eared Owl; and rails are also generally not mentioned; the rails at Huntley Meadows Park, VA, are an exception because birders stay on the boardwalk.
The second circumstance concerns private property: If the property owner does not want birders, the sighting will not be reported--at least in a way that identifies the location.
Please keep your reports concise (no lengthy trip reports, please), and provide the following information:
Full SPECIES NAME.
NUMBER of individuals of each species (estimates for big flocks are fine).
Age and sex, if relevant (important for gull observations, for example).
Location, including COUNTY and STATE (there are four Middletowns in MD).
DATE of observation ("today", "yesterday", "Saturday", etc., are not as helpful).
TELEPHONE NUMBER where you can be reached on Tuesday between 10 a.m. and 1 p.m.
DIRECTIONS to little known places (your favorite local hot spot may not be familiar to the Voice compiler or to other nonlocal people); page numbers and map coordinates from the DeLorme atlas/gazetteer are extremely helpful.
Access limitations, if any; and, for birds that are on private property, whether the owner does not want birders, if you know.
Unusual behavior seen.
For RARITIES, a description of features YOU ACTUALLY SAW (not what is in the field guides).
Thanks in advance for your reports. You can be sure that they will be read. Don't be disappointed if your sighting isn't mentioned; when there are a lot of reports, summary comments sometimes have to be made. There are times, however, when every report is used in writing the Voice, for example, during the hot days of summer. -- Voice of the Naturalist
