While there I gave three talks and lead a couple of bird walks, one of which was on the Plum Orchard Trail behind Nature's Classroom. We had 30 or so folks along, including some keen young bird watchers, and the birding was fairly good, considering it was a hot, muggy afternoon. We had lots of red-eyed vireos, eastern kingbirds, a green heron, immature white ibis, little blue heron, tricolored heron, pine warbler, four woodpecker species, and a noisy flock of brown-headed nuthatches. But the most interesting sighting happened right at the end of the walk on the sandy pool of water behind Nature's Classroom.
As we returned on the loop trail, one of our group spotted two shorebirds out on the pool. We initially thought they were spotted sandpipers because there were lots of spotties around and because they were teetering their tails the way that spotted sandpiper often do. But as they came out of the vegetation and walked closer it was clear that they were the larger solitary sandpiper. And they were really behaving weirdly: running around excitedly, bobbing almost constantly, looking into the grass.
That was when the object of their attention slithered into view: a banded water snake came gliding toward the birds. The birds seemed to be conflicted about this: should they run or should they fight? As soon as the snake would head away from them, the solitaries would chase it. If the snake came toward them, they scampered away. Certainly the snake was too large for them to kill and eat, and I'm not sure that the snake could have subdued the sandpipers, so they were left to perform pantomime parries and thrusts with no actual attacks.
This was my first trip to St. Marks—one of our oldest national wildlife refuges. What a fantastic place it is! I'm certain I'll be back again for another visit.
