Crows swarming over the Rio Grande and bosque this afternoon reminded me of Alfred Hitchcock’s movie “The Birds.”  A pair of Sandhill Cranes were trying to land on the river, but they were having a hard time making their way through the swarm of crows. They tried flying through the crows two or three times before the crows thinned out enough for them to land. Each attempt they would start down, zig zag a few times, pull back up and circle around before making another attempt. On one of their circles they got close enough for me to get a clear shot of them above the crows. A flotilla of geese were leisurely floating down the Rio Grand to where they spend the night about a quarter mile from where I was standing.  When they saw me on the bank they turned into the current and started treading water, staying in the same spot for some time while they discussed among themselves whether or not is was safe to float on by me.  They finally decided to stay in the water and continued on their way, hugging the far bank as they floated past me. A couple of ducks floated down after the geese, but they decided it wasn’t safe to float on by me and took flight.
