Arriving in the park a bit before noon, first stop was the visitor centre and Tulip Tree Trail. The main target was Prothonetary Warbler, a species that I've narrowly missed on past visits here. It wasn't hard to figure out where to go as there was a crowd of birders intently scanning a patch of swamp. The birds had been showing, but were not around when we arrived. Fortunately it wasn't long before we heard and then saw a couple individuals.
They didn't seem at all concerned with all the birders and this guy spent some time foraging quite close to the boardwalk.
This was a promising start to the day and I hoped the trend would continue on the next stop at the marsh trail. A Yellow-throated Vireo was the first bird encountered there.
I happened upon this struggle of life and death as this toad was preparing to meet its end.
After leaving the park, I checked into the nearby Keith McLean CA where American Avocets and Willets had been seen. Both appeared to have moved on but just when preparing to leave, another birder pulled in to tell us that a Yellow-Headed Blackbird was being seen on the causeway outside the park. This would be a lifer for me and fortunately within a couple minutes was watching this gorgeous bird sitting on a nest in the marsh.
