APPENDIX I 



INSTRUCTIONS FOR RAPTOR SURVEY ROUTES 



Winter routes should be completed between January 1 and 

 January 15, inclusive. Summer routes should be completed 

 between June 1 and June 15, inclusive. When unavoidable, 

 surveys may be extended to the 22nd. 



DATES OF 

 SURVEY 



WEATHER Do not conduct survey when (1) wind velocity exceeds Beaufort 3; 

 CONDITIONS (2) sky condition exceeds 2. 



STARTING TIME 



Start routes as near 11:00 AM as possible, 

 route within 4 hours. 



Try to complete 



SURVEY Drive route at 20-25 mph, stopping only to identify and record 

 PROCEDURES raptors. Binoculars should be used to locate and identify 



raptors. Spotting scopes may be used for identification, but 

 not for scanning an area. Carry a field guide for aid in 

 identification. When possible, classify raptors as adult or 

 immature. Make a special effort to avoid recording the same 

 bird more than once. Record time, mileage, wind velocity and 

 sky condition at start and finish. Use the 2400 hour system 

 for recording time. 



OBSERVERS If possible, two people should conduct the survey along each 

 route. Include names of both observers on the report form. 

 Where only one observer is involved, extra time may be required. 



Suggestions for Estimating Wind Velocity 

 Smoke rises vertically. 



Direction of wind shown by smoke drift, 

 but not by wind vanes. 



Wind felt on face, leaves rustle, 

 ordinary wind vane moves. 



Leaves and small twigs in constant 

 motion; wind extends light flag. 



SKY 

 CONDITIONS 



- Clear or a few clouds 



1 - Partly cloudy or variable 



2 - Cloudy (broken) or overcast 



4 - Fog or smoke 



5 - Drizzle 

 8 - Showers
