Winter Raptor Survey (WRS)
The WRS monitors winter raptor populations by conducting roadside surveys in mid-winter (Jan 10 to Feb 8). Participants create their own route in their area and drive it once and count all of the raptors seen.
1. This being a road survey, THE MOST IMPORTANT CONSIDERATION IS SAFETY. Use a designated driver if possible.
2. Design your own route. But first check with coordinator to avoid overlap of routes (some are not yet mapped).
3. Dates: You choose the day: Jan. 14 - Feb. 12 inclusive. Usually I will extend by a few days – but please try to do within the stated dates so as to keep this a “mid-winter” survey.
DO YOUR ROUTE JUST ONE TIME. Do not repeat for the sake of “ improving” the numbers –THIS IS CRITICAL!.
4. Time of day: Mid-morning to mid-afternoon.
6. Record hours of survey time and miles driven.
7. Note the average approx:
8. Record the following as possible:
Harriers: Ad. male or female; or immature
All other raptors (age BE, RS, GE)
Don't linger over birds you can't easily age or sex - just record species.
9. Any shrikes?
10. You may stop at good (and safe) vantage points to get out and scan/scope more thoroughly. But do not go on hikes looking for birds.
11. IMPORTANT !!! Coordinate with others in your county to avoid route duplication.
12. For consistency sake, I will not accept routes that are primarily on interstate highways or done after Feb 22.
