2018 Season Summary
The 2018 count was the 36th consecutive season of monitoring diurnal raptor and turkey vulture migration at the mouth of the Detroit River, and the 21st year of consistent coverage at Lake Erie Metropark. There were 551 hours of data collection with counts conducted on 81 days between 1 September and 30 November. 120,712 total turkey vultures and raptors of 15 species were counted, which includes 6 unknown buteos, 3 unknown falcons, and 5 unknown raptors. This total was only 5% below the long-term average (LTA) for the count site. We compare this season’s totals to the respective LTA for each species since 1998. Turkey vultures (25%), American kestrels (24%), merlin (19%) and peregrine falcons (69%) were the only species counted above the LTA. Osprey (-68%), bald eagle (-55%), Cooper’s hawk (-74%), northern goshawk (-89%), broadwinged hawk (-25%), Swainson’s hawk (-28%), red-tailed hawk (-32%), rough-legged hawk (-39%) and golden eagle (-50%) were significantly lower than their respective LTA (where values >15% are considered “significant” for the count).
