Immature (older than first-year) because of uneven trailing edge to wing.
Detalles de la observación
All birds seen were fairly high - of the unknown-age birds, 2 were juvenile/immatures. Observed intensively from 1155-1207 and counted 6 birds during this time - first saw 2 circling over the Scratchgravels. Observed 2 individuals gliding SW more or less overhead, separately. Besides the 2 which passed over, I saw 3 circling together for a while over the Scratchgravels gaining altitude, then lost sight of them distant to the NE. When I lost sight of these 3, the second of the 2 birds that passed over, an immature, was overhead. Shortly after that, I saw 2 additional birds circling over the grass-covered hills SW of me, distant, bringing the total so far up to 6. This second fly-over bird gave me the best look of all those seen - it circled for a while, high in the vicinity of the Scratchgravels, then glided steadily SW, then circled some more generally over the property, then continued on to over the SW hills, where it circled some more. At 1226, I spotted one adult and one juv/imm circling low over the Scratchgravels together, rising up, and then heading SW. At 1236, I watched the same 2 individuals circling over the hills to the SW, getting miniscule and quite high, with 2 others, both adults. Based on the time and trajectories of the birds previously observed and the age-classes (only one of the 6 previously spotted was an adult, and in this group of 4 there were 3 adults), I concluded confidently that these were all different individuals. I lost sight of them all very high to the SW - I last saw 2 of them heading more or less south, and was able to follow one of these until it appeared to be over the mountains S of Hwy 12 before I lost sight of it. At 1253 and intermittently in the next ca 10-15 minutes, I saw a large, dark bird with notable dihedral and steady flight circling low over the Scratchgravels, though I was not able to age it at that distance. I briefly saw 2 considerably smaller soaring birds circling with it at 1253 but did not spot them again - I suspected they were Buteo but can not positively rule out CORA given brief distant views.
