I was in Rochester yesterday, but back at home this morning, and still have a Yellow-billed Cuckoo calling. The call is a harsh throaty "Kowp.... Kowp.... Kowp.... Kowp.... Kowp.... Kowp.... Kowp.... Kowp...."
I had decided that I just couldn't describe the differentiation of Black-billed and Yellow-billed Cuckoo calls as John requested, but regarding _this_ particular call, I listen for the differences between hard "C" and harder "K", and between a mellow "oo" and a raspy hollow "owp". (this just breaks down a transliteration found in some field guides; I'm not asserting that it should be meaningful to anyone other than me) Out the window right now, I'm watching a pair of Great-crested Flycatchers gathering nest material from the garden! My responses to Richard's Mockingbird questions: >> 1, How large a collection of different sounds can one bird make? The brain's the limit! >> 2. I recognize some of the sounds. Would a cardinal be confused in hearing >> his call? Perhaps momentarily, but the Mockingbird's habit of varying the calls, and delivering each one in triplicate, quickly gives the game away >> 3. Are the sonograms of a mockingbird and a cardinal about the same, or can >> you tell them apart. I'm not up on sonograms, but I assume they can be drawn at various resolutions, and that a low-res similarity would break down at sufficiently high resolution. >> 4. Mockingbirds migrate. Can you tell where they spent the winter by the >> songs they sing? I had a Catbird around home one summer who sang "chuck-wills-widow". I couldn't say _where_ he learned that, but l don't think he made it up! >> 5. Do mockingbirds make calls of predators like owls or hawks? Yes. -Geo Kloppel -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://email@example.com/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
