Migrants arriving and some that haven't left

This morning I saw my first White-crowned Sparrows of the season, birds that breed primarily in mid and high elevation willow carrs in Colorado then migrate down to lower elevations to their winter habitat. At least 2 White-crowns were in a flock of 8-10 Song Sparrows.

On the other end of the spectrum was a female Common Yellowthroat, a bird that breeds in the lower elevation areas of Colorado including Canon City and that should be migrating to or near Mexico for the winter. Nearby I heard two likely Marsh Wrens making their "chuck" call and buzzy song.

Two Belted Kingfishers chased each other unrelentingly, emitting their rattle-like call as they flew. One Eared Grebe dove in a local pond searching for food. The grebe may be a migrant. An Osprey perched above the pond, also searching for food.
