The Blue Jays in the park have been making lots of noise these last few weeks. Most of the time it seems to be a false alarm, but this afternoon they were helpful. They helped me find a juvenile Red-tailed Hawk and an Accipiter (either a Cooper's Hawk or Sharp-shinned Hawk). They were west of the Conservatory Garden and east of the Compost Heap.
All of the pictures but the last one are of the Red-tail. It was eating something with a thin band on each leg. I didn't stay long enough to see if they got swollowed.
