April 25th – Moving On

A beautiful "white morph" White-throated Sparrow - photo by Caleb Scholtens

There was a much different feel to Ruthven this morning. Sure, there were White-throated Sparrows singing at first light but after that it was quiet….very quiet. Right off the bat it was noticeable that the Dark-eyed Juncos, that had been staying around for the past several days, fattening up on the bait in our traps, had moved on. Yesterday it seemed like they were everywhere and we handled 26 of them (2 banded; 24 retraps) but today had only 5 retraps and saw only a few above that. There was very little activity (other than Tree Swallows) along the River and the forest was dead. So many of the birds that had been waiting around for better migration conditions appear to have taken advantage of the conditions last night and to have headed north. Unfortunately, it looked like no migrants from farther south had moved in to take their place.
