Both Mourning Warblers this week were left in place for removal trials. Tuesday’s bird was not visible on the 25th because it had been covered in fresh mulch. Thursday’s bird is still there as of Saturday morning.
There was more mourning for me this morning, as I found a nearly identical bird to the casualty from Tuesday: Hatch-year Mourning Warbler; indeterminate sex; fat = 3. Here is another youngster on its first journey from the boreal forest to perhaps Colombia or Ecuador, cut down in perfect health from a stupid window in the southwest alcove.
