The 425th edition of the Chicago Ornithological Society's North Pond Bird Walk took place Wednesday, 5 June 2013 at North Pond in Chicago's Lincoln Park.  We tallied 43 species.

There are still a few lingering migrants in thepark.  Some that we recorded were EASTERN WOOD-PEWEE, YELLOW-BELLIEDFLYCATCHER, ALDER FLYCATCHER, GREAT CRESTED FLYCATCHER, andSWAINSON'S THRUSH.  Late migrating warblers included a MOURNING WARBLER, a nice male BAY-BREASTED WARBLER (singing his head off,  too), and a BLACK-THROATED GREEN WARBLER, plus also three COMMON YELLOWTHROATS and two YELLOW WARBLERS.   There was also one PINE SISKIN.

The CANADA GEESE, WOOD DUCKS, and MALLARDS have all produced young, and there are still a few fresh broods showing up.  Juvenile EUROPEAN STARLINGS are filling the air with their begging calls.  A couple of us heard what sounded like Fish Crows; we presume these were likely young American Crows, but we weren't able to track down the source.

After this week's walk I found an OLIVE-SIDED FLYCATCHER at the AlfredCaldwell Lily Pool just across Fullerton Ave from North
Pond.  Just after, I bumped into Ward Boulton and Rob Wells, who had  also located the same bird.

The species list appears below.
