American Robin foraging on the lawn in front of the National Gallery. 31 March 2010.

There are three different songs here sung by a Western Meadowlark. The first repeats three times, the second song repeats 4 times, and the third song is repeated three times. This was recorded on Marble Hot Springs Road at the 2nd 90 degree turn as the Meadowlark sang from the telephone wire above. In the background you will hear cows moo and a few other birds call as well, but the Western Meadowlark is clearly the focal subject of the recording. This was recorded with a Fostex FR-2 and Sennheiser shotgun microphone, ME66. The photo attached is a spectrogram of Western Meadowlark made in Raven Pro. (taxonomy:binomial="Sturnella neglecta")

American Robin bathing in the fountain of the National Museum of the American Indian. 10 May 2011.

This bird was recorded across the street from our apartment. I have not been able to actually see the bird, but for weeks I have been listening to it sing/call every morning. To be singing on our busy street (Massachusetts Ave, NE, just a few blocks from the Capitol in Washington, DC), it must be a common bird that thrives in the city, so I'd like to know this city dweller's name. I'll update this note when I learn who it is. UPDATE: HOUSE WREN! Thank you, Mark, Perry, Martyn, Lang, Kristen, and Seth! June 15, 2012, recorded with a Fostex FR-2, Sennheiser ME-66 Shotgun mic, Rycote windscreen. Sonnogram created using Cornell's Raven Pro Sound Analysis software. (taxonomy:binomial="Troglodytes aedon")
