Waterbird Count, April 11

Today was yet another day of very poor visibility, only this time it was considerably colder, with an average ambient temperature of 33 °F, and easterly winds averaging eleven miles per hour.  The highest visibility was approximately two miles, and only lasted for approximately the first two hours, and got increasingly worse as the fog thickened and the rain began to fall.  Even so, there were still a number of waterbirds seen moving through the straits.  In particular, the high numbers of Long-tailed Ducks moving through in the early hours I found intriguing.  Since I could only see approximately three quarters of the way across the straits at best, I wondered how many more waterbirds were migrating or loafing, but concealed by the fog and rain.
