Today I went on a Denver Field Ornithologists birding hike, led by David Suddjian, at Ken Caryl Ranch.  It was a marvelous opportunity to listen closely to birdsong.

Here is one of the star singers, an Ovenbird, whose loud volume is matched only by the difficulty in spotting the bird (let alone photographing it, as you’ll see by my picture).

Here’s a couple of other birds who were vocalizing, if not always singing.

In the afternoon I went into the Bear Creek Greenbelt and found two of the owls.

Looks like this Broad-tailed Hummingbird is still incubating:
