I spent a couple of days working at St. Croix State Park this week and led
small bird hikes in and around St. John's Landing on Tuesday and Wednesday
morning.
At one point, we found a singing Chestnut-sided Warbler near the river and
heard another one immediately adjacent. The second one proved to actually be a
Yellow Warbler singing a perfect Chestnut-sided song. We watched it sing, and
at one point, it sang the Yellow Warbler song once, then went right back to the
Chestnut-sided song. I can't remember ever noting this before and I wonder how
these two birds can be such close neighbors...and whether the Yellow Warbler
successfully attracted a mate--we never saw a female. I didn't know warblers
would sing the 'wrong' song; and sing it well.
Also of note at St. John's Landing:
- Scarlet Tanager pair feeding a chick on a relatively low nest (a highlight
for ANY bird hike!)
- Purple Martin pair in the nest box in the open field (I've never seen one at
St. Croix...in fact, they're not even on the park's checklist)
- Blue-gray Gnatcatcher near the river (listed as Occasional in the park)
- lots of Eastern Towhees (fun bird this far north!)
- Northern Parulas and Mourning Warblers frequently heardShawn
