Good Morning Barbara,
You mentioned the juv. RED-shouldered HAWK. Could it be the same youngster, who perches frequently on the Boardwalk lamp post on one claw, holding up the other? Clearly the PIGEONS aren’t alarmed by the hunter’s presence as they calmly sit on their wire. How do they know they are safe from this hunter? Is the held up claw injured, preventing hunting? A watchful adult RED-shouldered HAWK is in attendance on a Trestle tree branch. Is it a concerned parent?
I was lost in my thoughts when a small HAWK lifted off right next to me and made my heart jump. Instantly I wondered:
“Is it a COOPER or a SHARP- SHINNED HAWK?”
These 2 species are so hard to differentiate! The short wings, small body and head size, pointed to a SHARP-SHINNED HAWK. With its 11 inches length it’s the shortest one of the Accipiter species. This smaller than a CROW predator is famous for its low flying, high speed hunting style through bushy vegetation. The SHARP-SHINNED HAWK impales the prey with a talon and plucks its meal since it doesn’t consider feathers part of its migratory feast.
For me the San Lorenzo River(SLR) is a source for enjoyable wildlife observation and relaxation. As I am beginning to read the 2015 Interim Management Plan (IMP) for the river’s mouth and lagoon, its apparent that the machinations of the river’s mouth are anything but relaxing for City staff. This IMP document serves as a Pilot Program on how to deal with the river’s summer lagoon and outlines a permanent solution for lagoon issues. So why is the City addressing the lagoon? Well, this formation of a costal river lagoon, created by the sand barred river mouth, allows the water to rise in the SLR Estuary Stretch( Laurel St bridge to river mouth) to such an extent that it floods the downstream neighborhood and the Boardwalk basement. This lagoon problem is created by the fact that Main Beach (and Seabright Beach for that matter) are now much wider (from Boardwalk to Ocean) than it they were prior to the construction of the Santa Cruz Harbor and its large breakwater. We have the Army Corps of Engineers to thank for the Harbor’s construction, as well as the levees. The IMP describes two flood control approaches for the lagoon: 1)Temporary Outlet Channels, 2) Head Driven Culvert. The process is complicated and involves many State, Federal, Local agencies. It seems like the ill conceived development planning of the Army Corps of Engineers has left the City holding the bag trying to manage an intricate balance of habitat preservation, environmental protections, flood protection and mitigation, resource expense and public safety. What would Santa Cruz look like, if a Calif. Coastal Commission had existed back when the levees, harbor and Boardwalk were first proposed? More next time and let me know if you have any IMP questions.
My friend & I were entertained by 2 male BUFFLEHEADS, who had set their mind on infiltrating a flock of COMMON GOLDENEYE. The 2 species share close water proximity, but the flocks keep to themselves. The 2 males obviously were determined to break the flock barrier. No matter how the COMMON GOLDENEYE group tried to dodge the BUFFLEHEADS, they couldn’t get rid of them. The flock tried to distant itself from the 2, who increased their swimming speed, dove & popped up smack in the middle of the them, prompting some agitated flock members to beak-dive out of sight. The 2 rebels just wouldn’t let up on their ‘break-the-flock-barrier’ mission and finally the COMMON GOLDENEYE flock consented to the 2 rogues right in their center. Oh! before I forget: the native BLACKBERRY bushes by the E. Riverside St. under-path are flourishing nicely after the rain.
Just signed up for the Santa Cruz Christmas Bird Club Count and I am encouraging friends to sign up as well. Chirps for you, jane
