This morning we took another walk at Union Village, saw some cool things, including our first Baltimore Oriole, still lots of yellow warblers, several common yellowthroats, lots of catbirds. Heard Wood Thrush and redstart.

Finally, we got great looks at a porcupine that we surprised while walking there!

Back at home, the first bobolinks are singing on the field, and the first hummingbirds came by this morning.
