Migration Monitoring at TTP-April 22-28

Still waiting.....
 
Only 46 birds were banded during the update period which is extremely slow for this time of year. Migration Monitoring stations across southern Ontario have had similar numbers for the week. Perhaps the birds are holding further south and just need a warm front to get them going! Species diversity has been lower than a year ago as only a few new arrivals were detected over the past week. Numbers of Myrtle Warbler have been gradually increasing although the major movements of this species as well as Ruby-crowned Kinglet and White-throated Sparrow are expected very soon. There were some unusual sightings since my last synopsis, the most notable of which was a flyover Dickcissel recorded on April 22! This was a first record for the bird research station and to my knowledge only the second for Ontario in 2005 (more sightings below).
