Chiming in again about COYE…. migrants may well be by-passing us, but COYE is an abundant nesting species at CSR. Usually the place is cacophonous with their songs. I’ve seen one male so far, and only for about 2 minutes. No others have arrived here yet. Same for House Wrens, they are thick nesting here, and I’ve seen one or two so far.
And an FOY Chipping Sparrow today - but they are usual after May 1 here. (Last year I had “0” in April, and 90 on May 2!!!). Other than that - with the forecast for lots of migrant passing over CO last night - it was obvious NONE of the stopped at CSR!!! I caught 4 birds today, 2 of them recaptured White-crowns banded earlier. Sigh.
