I did a little birding and naturalizing in this municipal park, a square of suburban woods and swamp. A few takeways:
That big tree with the blocky bark? It’s not a Chestnut Oak, but good old Eastern Cottonwood (Populus deltoides), dominant in habitats like the lake shore. And often growing straight up, just to confuse visitors from the east and west.
I also spotted a Question Mark butterfly (Polygonia interrogationis) and a couple species of mystery mushrooms.
