Earlier this summer, I began watching a marsh/pond area. The beavers and herons were quite entertaining, but the Virginia rails, sora rails, and common moorhens took me and other birders by surprise. Having documented their presence during Breeding Bird Atlas safe dates up through early June, I did not return to the area until this evening. We've decided to call it Moorhen Marsh, and not reveal its location outside of a small circle of friends.
It was still there, but I didn't recognize it at first. The cattails and rushes were well over six feet high. Bright green duckweed covered the water, and patches of mud had emerged as the water evaporated. I was not surprised as dozens of mallard ducks took wing as I climbed within view of the first section of the marsh. Hundreds of blackbirds - I assume redwinged blackbirds - did fly bys over and around the marsh and ponds. Chimney swifts twittered by, and high overhead, several night hawks were heard. Two months ago I could count on hearing spring peepers, bullfrogs, and greenfrogs. Tonight, no peepers peeped, only a couple green frogs called, and no bullfrogs were heard anywhere. Where once two dozen bird species could be heard and spring peepers would drown out the highway noise, a kind of quiet one experiences after a major event like a wedding or a vacation was present.
No rails or moorhens were heard. Still, activity near the marsh and the swamp by the river drew my attention. For an hour, I listened to the croaks of great blue herons as they came into roost and settled in for the night. While I can't be sure, I believe at least eight came in to roost in the dead trees and there could have been as many as twelve. An occassional green heron was also heard, but none were seen.
As night began, I watched a lone muskrat swim across open water towards a clump of cattails. As I scanned with binoculars, I noticed that other muskrats were already in the shallow eating contentedly. Even with my most stealthy sneaking about the ponds, the beaver saw me first and cracked his tail against the water, startling me and reminding me I am watched as much as I am the watcher. Two sizes of bats acrobatically patrolled the area, eating insects, but not enough of the mosquitoes to keep me from being bitten repeatedly. I do hate being bitten.
It was time well spent. Getting to know the marshes and ponds at this site later in the year reminded me of the many changes that occur in a marsh and a pond as the summer waxes and wanes. I thoroughly enjoyed getting reacquainted. I can't wait to see what this place reveals to me on my next visit.
