1st MAPS session – June 5th, 2009

Today was the first session of our summer MAPS (Monitoring Avian Productivity and Survival) banding programme. A mark/recapture study, the data collected through MAPS helps us determine the survival and success of nesting bird species in the park and is a measure of ecosystem health.

The day started cold and quiet and it certainly looked like the banding session would end up as a dull bask in the sun for the banders but as the morning progressed avian life began to blossom. A late migrant Blackpoll Warbler began calling form the front of the mansion and a cacophony of cuckoos, both Black-Billed and Yellow-Billed, arose. A lone Purple Martin investigated the nesting box in the parking lot forlornly.

The highlight of the day was the presence of a male Cerulean Warbler in the valley behind the station. Decent, but fleeting, glimpses were obtained and the bird called on and off throughout the morning. The banders were highly entertained.
