During the past several days I have heard the Gray Catbird fledgling giving it's begging calls repeatedly but when I first heard it I thought it was an American Robin or another bird. However I finally watched the fledgling as it gave the calls and I decided to record it as there were only about 3 other recordings of what Xeno-cantu lists as juvenile calls. I have uploaded the recording with attached sonogram to my Birds and Nature blog for anyone who might be interested in this different, almost insect-like calling.
BTW, I did not go to Holcim Wetlands today and don't know if the TRICOLORED HERON was seen-hopefully anyone who might have gone out there will post.
