When I opened my garage door to head out birding this morning, I heard a Say’s Phoebe singing down the street. The bird was at a house where it has held territory for many years now. A short time later, along Boulder Creel near 75th Street, another Say’s was singing on a territory also held for many years. Fascinating synchronicity of arrival.

In walking through Cherry Creek State Park this morning, I saw my first Say’s Phoebe of the season as well!  (And a Western Meadowlark!)

Yesterday afternoon (3/19), I opened my door to one singing in the top of a neighbors' cottonwood (Centennial, Arapahoe County). My first of the season, as well.

Glad to hear there are Say's Phoebes on the move.  These are right on time and it jives well with the weather pattern.

Range map for Say's Phoebe in Jan-Feb:

Note the maxima of observations as well as the general pattern of where these birds would originate to make it to Colorado, then look at the following wind map:

The green circle on the wind map is Boulder, CO.  Makes good sense why there would be Say's Phoebes coming to town these past two days.  

Interestingly, maybe the birds from the 19th came from Texas, but the birds from the 20th are more likely from a different location in the SW US.  

There were also a few different odds and ends showing up today that are noteworthy weather-wise: Sagebrush Sparrow makes some interesting sense with the Southwest origin, Common Grackles are advancing farther north, Double-crested Cormorants are showing up in Boulder county, American White Pelicans are found in droves, Sandhill Cranes are passing through, and Osprey are making their first of the season appearances.

Thanks for the postings, it made me look harder at the situation.

Thanks, Bryan. So great to have context for what we see in the field.
