Hi Folks

Still keeping an eye on the shore. The most interesting change was  
the increase in Black Ducks. Before there were less than 6 in the  
area. The only shorebirds were the killdeer in Ash Creek. Off shore  
continues to be barren except for Double-crested Cormorants.

If one compares this year with last year, just about all the numbers  
are down.
Looking at the ratio of first winter gulls to total gulls

Ring-billed 3.4% first winter this year    5.2% last year
Herring 10.3% first winter this year    14.5% last year
Gr. Black-backed 21.8% first winter this year  23.7% last year.

Obviously this is little more than anecdotal evidence, but the trends  
are consistent and by spring I should have enough data for  
statistical analysis
