Kurt, It's juat all in how we remember things. I had read Rising and his description of the "chimp" sound. It wasn't until Bonnie compared it to the "bark of a tiny day" that I really remembered it. I'm sure it's the same sound Rising is describing in a different way. What works best to file it away in your auditory memory is probably different for everyone. For me, Bonnie's description was very easy to remember. Good Birding, Darius Ecker (dariuse@abs.net) Columbia, Maryland USA >Bonnie, > >Interesting. I would be curious to know the text from where this "barking" >description derives. The best description I have read is in Rising's "The >Sparrows of the US and Canada" which describes the loud distinctive call note >of Songs' as ".. a distinctive tchenk, tchip, or chimp, and often is a useful >aid to identification." (p.191 in the 1996 edition). Most of us over here in >the "hinter lands of Ol' Virginny" tend to agree with Rising, and I use the >"chimp" mnemonic during walks because it is easy for beginners to remember. >And I agree, the soft spoken "tseep" call note is a tough one to ID, >especially when nearby Swamps' are doing their "tsup" call (which is a bit >louder and having more emphasis on the ending portion whereas the Song is >softer, almost trailing at the end...oh, and Rising doesn't describe this >Swamp call!). > >Kurt >
