This call is *very* similar to American Avocet. The frequency and overtone pattern are very similar. The shape is slightly different... It's a bit more peaked like an upside down V rather than an upside down U.

25. Double-crested Cormorant

    Number observed:  4

26. Least Bittern

    Number observed:  1

    Details

    It flew by right in front of me, landing in the reeds just a few feet away. Small size clearly smaller than green heron. Otherwise a bittern/heron shape.
    
    After it landed in the reeds near me, I went closer trying to find it visually. I couldn't find it, but as I got close to its location it called out loudly. I couldn’t believe it.
    
    Prior to all of that I had heard it call from a distance.
    
    First recording is when it called loudly from the reeds right next to me. Second recording is the call captured from a distance.
