Monday September 16th was our 20th survey of the 2019 hawk migration season at the Jewel Basin Hawk Watch northeast of Bigfork, and the second consecutive day with more than 100 birds counted, as the migration is picking up! Daily totals otherwise have been a bit lower than previous years due to foul weather, although our season totals of 740 birds over 20 surveys are both above average numbers for the early part of the season.
We have also reached several long-term benchmarks this season. For example, a Sharp-shinned Hawk (naturally) on September 2nd was the 28,000th raptor recorded at the Jewel since our surveys began in 2007! We have also now counted more than 100 Prairie Falcons, 600 Bald Eagles, and 13,000 Sharp-shinned Hawks.
Hopefully by the time you read this article the weather has taken a turn for the better, with sunny skies and strong Southwestern winds. If so, perhaps we will get to enjoy Accipiters peaking a 1,000 in just a single week, as observed in previous years!
Here are the totals from the survey days between August 25th and September 16th, with 740 birds of sixteen species recorded (only Rough-legged Hawk and Gyrfalcon have not yet showed up this season. This hawk watch depends heavily on the efforts of volunteers, most of them members of Flathead Audubon, as well as on direct financial support from both Flathead Audubon, Flathead National Forest, and Montana Fish, Wildlife & Parks. This year Kat Petersen is working as the technician hired to conduct 30 surveys.
