FIELD NOTES Doug Bell April 5, 1988 well. Saw a pair of kestrels sitting atop a large snag on the small peak to its south of goat rock. The kestrels copulated - unusual - the ♂ did about 5 purring motions. 10:10 - the ♀ is definitely in at least partial shade in her scrape. 10:06 - ♀ shifting on eggs again, stood up straight, peered out, resettled. 10:42 - Male in, female out of pothole, screaming. Both landed in snag (⊙), on branch next to me mother. Female tugged at prey in males foot, didn't release right away. Female tugged food away, flew to snag (⊙) top, ate. Small bird < jay sized? Male flew into pothole, landed directly on scrape, ate. about 10:46. He settled in scrape, then got up, walked to ledge, ♀ screamed couple times, pissed off hek-hek, both birds looking up. Then male returned to sit settle on eggs. Female flew from snag (⊙) to low trees below (⊙), sitting in shade. 11:02 - ♂ in scrape. April 6, 1988 08:40 - Female screaming on ledge. Flew back to pothole & snag (⊙). Sitting atop it preening. Male in pothole (X), on scrape. Monty Kivinen had mentioned some good pointers on id'ing male vs females adults. Females look more slate gray, have p"tips that tend out to protrude below the tail, appear more scruffy, a fluffy, as they are more advanced in molt - may also have dropped ∞*7 by now. Males are more dark blue, appear "meaty".
