Re: Coopers Hawk (accipiter cooperri)

07/18: I have again observed some proning behavior now from the hawklets, mainly it seems from the smaller (and likely male) individual. The larger female although off nest tree frequently now, still seems to be using the nest itself or the branches very close to the nest as a resting area. Over the...

Re: Coopers Hawk (accipiter cooperri)

07/14: I finally was able to get a confirmed sighting of the second hawklet off the nest, although I suspect it could easily have been off before that. Around 06:55 after the arrival of an adult in the area, I spotted the second hawklet flying and vocalizing from the area just east of the nest tree ...

Re: Coopers Hawk (accipiter cooperri)

07/12: I am putting down July 12 as the first confirmed fledging, as I found one of the hawklets around 08:30 in the tree beside the road which is close and slightly NW of the nest tree. This tree is the same one the adult female has been regularly roosting in. The second hawklet was not immediately...

Re: Coopers Hawk (accipiter cooperri)

07/09: I was able to witness another interesting entire sequence in the evening, at 18:25 I observed the male fly into the park from the west and land nearby to the nest. The female was roosting in one of her favorite spots in the close tree just beside the road. The male did not make any audible ki...

Re: Coopers Hawk (accipiter cooperri)

07/04: Catching a brief feeding on the nest, as well as the hawklet activity after the feeding provided good views of the feather development, with increasing loss of down and good emergence of all the primary and secondary flight feathers: https://www.youtube.com/watch?v=WZFwEUNvsMQ https://www.you...

Re: Coopers Hawk (accipiter cooperri)

07/01: I was fortunate enough to catch the adult female very low in the nest tree only about 10 feet off the ground which allowed for some good close footage. https://www.youtube.com/watch?v=5MmIIwAFMFc https://www.youtube.com/watch?v=_yvhM_HvU3Y https://live.staticflickr.com/65535/48175819097_0edce...

Re: Coopers Hawk (accipiter cooperri)

06/26: Further development of the hawklets, around noon time there was a feeding in progress on the nest, with both hawklets nicely visible and at times standing up fairly high to face the female and grab pieces of food. One of the hawklets stands up and lets off a slice, and there are definitely pi...

Re: Coopers Hawk (accipiter cooperri)

06/21: approx 18:20, there was already a feeding in progress on the nest when I arrived at the park entrance, observing the feeding and just taking still shots, there were two hawklets much more clearly visible reaching up as food was offered. These two were definitely noticeably larger and could be...

Re: Coopers Hawk (accipiter cooperri)

06/14: 17:51, the male arrived in the park from the east carrying a food item, and again there was a rather interesting sequence of interaction that seems quite different than the typical pattern from previous years. After walking around and coming back to the nest side, the male appeared to have fo...

Re: Coopers Hawk (accipiter cooperri)

06/09: From several false alarms over several days of seeing the male around the nest and hoping to catch an actual food exchange which might confirm food being brought to the nest, I finally got definitive sign of a feeding. However from the female's behavior (especially high sitting position and s...

Re: Coopers Hawk (accipiter cooperri)

Re: Coopers Hawk (accipiter cooperri)

It appears perhaps unfortunately that the nesting attempt at CSSP park has ceased, at least for the time being. However there is still presence by the pair and some interesting behavior. - 05/17 a visit to the nest area didn't seem to have the female visible on the nest, although on many nests it ca...

Re: Coopers Hawk (accipiter cooperri)

Re: Coopers Hawk (accipiter cooperri)

Apr 21 - I saw the adult female sitting on the nest for the first time in the morning in incubation position, which is likely at least a sign of impending egg laying, but might or might not be a definite indicator of actual laying. Apr 23 - I did not see the female on the nest either of the times I ...
