Re: Coopers Hawk (accipiter cooperri)

This is a wonderful video absolutely chock full of top notch information on the Coopers, quite a bit of these same findings are also part of Dr. Rosenfield's book which Hancock House just published. https://www.youtube.com/watch?v=nLj_R30ZKaA I was told by the author that the hardcover version has a...

Re: Coopers Hawk (accipiter cooperri)

Aug 17: In the morning I found one of the adults roosting near the nest area, it was raining out and the adult just appeared to be idle enduring the showers. There was not any sign or vocalizations of either of the fledglings that might food beg from the adult which suggests they weren't around. Abo...

Re: Coopers Hawk (accipiter cooperri)

There has been progressively greater activity of the fledglings both in and out of the park, with the fledglings spending more and more time both further from the nest in the corners of the park, and sighted on the streets adjacent (about 100-150m N of the border of the park). Aug 3: In the morning ...

07/24: Fledgling hiding in the tree branches along the NW border of the park. https://live.staticflickr.com/65535/48369220351_68dc95aa9d_c.jpg I observed an interesting sequence, starting with the male in the lower part of the nest tree around 19:15, after several minutes he suddenly reacted to some...

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...

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)

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...

These two were definitely noticeably larger and could be...

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...

This is indicating that the female is spending substantial amounts of time in the park ...
