Predator And Prey   1 comment

On Thursday of this past week, Sabino Canyon Volunteer Naturalists were teaching two first grade classes about predator and prey in a program we call “Now You See It.” My responsibility for the month of April is to coordinate the Thursday schedule with the teachers. Once the children are in the canyon, my job is one of “managing by walking around.”

While in the riparian area near the creek and dam I could hear a nearby cooper’s hawk. Following the sound, I spotted him on a dead limb high above the creek where he had caught a small bird. What a “real time” example of predator and prey for the day’s lesson. What follows are images and a video of the encounter, which I shared with the children.

Predator And Prey — Cooper’s Hawk

The varying modes of flight exhibited by our diurnal birds of prey
have always been to me a subject of great interest,
especially as by means of them I have found myself enabled
to distinguish one species from another,
to the farthest extent of my power of vision.

Watching Over Nest On A Windy Day   1 comment

Cooper's Hawk Over Nest (1 of 1) blogCooper’s Hawk Above Nest In Sabino Canyon (October 31, 2016) — Image by kenne

Wind gusts ruffle the hawks feathers while watching over the large nest
high in an ash tree in the Sabino Canyon riparian area above the Sabino Creek dam.
Since this area is near where the Sabino Canyon Volunteer Naturalists (SCVN)
conduct their nature program for elementary school children,
many students will have a opportunity to see activity near the creek
adding to the excitement of being on a field trip in Sabino Canyon.

Cooper’s Hawk On Black Tree   2 comments

Cooper's Hawk (1 of 1) grunge blogCooper’s Hawk On Black Tree– Grunge Composition by kenne

All night black tree
shapes wrestled their dark
angels or assailants; the deep woods
wracked by shattering, cracking;
then rain drove straight 
sheets like a wave’s crash
wrenching leaves and birds’ nests
from the branch, battering
grain flat in the fields;
mice, rabbits in their burrows
drowned.
At first dawn, soft
mists down the valley rise till
light strikes, enamelling
each emerald green leaf
splattered clean.

When not mornings in Sabino Canyon, I’m usually running the streets in our community, Tanuri Ridge. While running one morning in early April, I noticed a hawk flying into a large mesquite tree. As I came back around I saw another hawk with a twig fly into the tree, and made a mental note to look into the tree while on future runs.

Over time the two adults finished the nest. In the beginning it was easy to see the nest because the mesquite tree was just beginning to grow new leaves. Now it’s difficult to see the nest, but usually can see one adult in the tree and another in a sentry position about 50 yards away. Until the chicks got large enough to see their heads above the nest, there was no way I knew how many were there.

About two weeks ago, as I ran by the nesting tree, some neighbors were at the tree’s base. One of the chicks was on the ground. At close inspection it was apparent that the chick had an injured eye. We were not sure what caused the injury, but since we now know the nest has three chicks, with four in the nest a sibling or a parent may have inflected the injury. At any rate it was apparent the chick had been pushed from the nest.

Yesterday, naturalist Anne Green posted a “chick update” on her blog “Your Daily Dose of Sabino Canyon.” Naturalists have been watching a Cooper’s hawk nest by the Sabino Canyon dam for weeks. With these chicks “branching” I decided it might be a good time to go photograph the Tanuri Ridge chicks. They are not branching, but I was able to confirm that the nest contains three chicks.

I spent time under and near the mesquite tree trying different photography angles. At first, one adult was in the nest with the chicks. Another was about 50 yards away. As I moved around, the adult in the nest was showing signs of getting anxious and left the nest to a perch about seven feet away. Meanwhile the other adult in a sentry position began a loud defense call, “cak-cak-cak. “

Getting frustrated trying to photograph the chicks, I walked to where the other adult was calling. As I walked toward the sentry tree, another hawk flew by responding to the calls, which looked like one of last year’s juveniles. At one point the sentry adult flew in my direction circling around back up to its perch.

I will keep watching the nest, but because of its location centered high in the mesquite tree, getting photos will continue to be very difficult, however, I enjoy the challenge.
