Tracking this female NG

10 December 4:55 P.M. Voyager RV Resort
1 female NG. The hawk came gliding and flapping through, quite slowly, at 60 feet elevation. Then at 5:25 P.M., the hawk was observed leaving the resort. This hawk was flapping with one-half depth wing beats. It also was at same elevation as female NG of 9 December. Also the hawk was in the same flight pattern as that hawk and at about the same time period. This information means that this raptor must be on its final sortie of the day.
Now I will track this hawk by getting into its flight pattern. I will spend many hours in different hawk watch sites, starting at about 4:45 P.M., until dark or near dark. My hawk watch positions might be separated by a mile or more, and that depends on the hawk.
That NG was black with no field marks. This was because the sun was near the horizon. No matter- Size matters; shapes matter; wing movement matters!
