MOLTING YELLOW WARBLER FLEDGELINGS, PRESQU'ILE PROVINCIAL PARK, BRIGHTON, ONTARIO, 7/2/2023

   The first two photos show a Yellow Warbler fledgeling which still has much of the down of a chick.  The last two photos show a more advanced Yellow Warbler fledgeling, with a lot less down.   Both fledglings could fly, but how far we couldn't tell.
