So sorry I forgot to post this earlier:

On Thursday evening (4/22) there was an Osprey circling over the Potomac, just below Great Falls, probably lured there by the presence of large quantities of smallmouth bass.  

Also pretty sure I saw a catbird in my yard the same day - I only saw it briefly so can't be absolutely certain.  

Not a bad Earth Day!
