May 19 [Day 86] (Piitaistakis Ridge site) The strong winds that started late yesterday continued throughout today with W-WNW winds 35-50 gusting 60 km/h to noon, diminishing to gusts of 35-50 km/h in the afternoon. The winds made the starting temperature of 6C feel rather cool after several days of warm weather and the high was only 12.5C at 1600, but it felt warmer as 100% cumulus, altostratus and cirrus cloud gradually cleared to 5-30% cumulus and cirrus in the afternoon providing plenty of sunshine. Despite the good migrating and observing conditions only 7 migrant raptors occurred between 0907 and 1610: 1 adult Bald Eagle, 2 juvenile Sharp-shinned Hawks, 1 juvenile Cooper’s Hawk, 1 juvenile Red-tailed Hawk, 1 subadult Golden Eagle and 1 probable juvenile female Prairie Falcon. Because of the high winds other bird species were hard to find, but for the second day in a row a flock of Canada Geese flew high to the east above the ridge: 12 at 1259 yesterday and 35 at 1325 today. These flocks almost certainly comprise unmated male birds. 12.58 hours (989.8) BAEA 1 (395), SSHA 2 (81), COHA 1 (17), RTHA 1 (121), GOEA 1 (2181), PRFA 1 (14) TOTAL 7 (3033)
