Migration Monitoring: May 24 - 30

Common Nighthawk by volunteer Lisa Chou

With all the rain we have been getting, the study area is turning into a swamp. It has been so flooded that there have actually been carp swimming in the net lanes! If it gets any higher we will need hip waders to check nets!

The flooding has created ideal conditions for species we don't normally observe. One of the volunteers had a Green Heron land in the water beside him while he was doing census.
The first Black-billed Cuckoo showed up on May 24 and they have been seen regularly in the study area throughout the week. The same day we had our first and only flock of Whimbrel fly over, something we don't often get to see.

On three occasions we have seen Common Nighthawks roosting, which we have never seen here before. One day before dawn we spotted one circling around the parking lot and watched it swoop lower and lower, passing through the trees as it searched for a place to settle in for the day. Eventually it landed on a tree right beside us, out in the open. It stayed there all day, clinging precariously as the branch swayed violently in the wind. We made sure not to disturb it and were able to get some great photos through the scope.

There has been a family of American Woodcock hanging around in the early hours. That explains why the pair that we saw daily in April seemed to disappear all of a sudden - they have obviously been busy!
