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!).
