Horned GrebeI am an optimist. But on Tuesday morning as I launched my kayak onto the Hudson River at 7:30 in the morning I was not filled with my usual sense that just around the corner was the next glorious sight. I wouldn't say I was feeling pessimistic, but rather more grumpy. And I was grumpy because the height of migration has passed--it comes and goes so quickly it is excruciating. I decided that nothing special could come my way ("all the best birds are gone" I said to a friend, sounding like a twelve year old having a tantrum). Armed with this bad attitude, I stroked south under a bluing sky toward Magdalen Island and the entrance to the North Tivoli Bay.
