I stopped at Tanner's Spring and saw loads of hermit thrushes. There was a flock of grackles overhead chattering away. They may have scared some of the smaller birds away. It's a bit hard getting around the park, because restrictive fences are up in preparation for Sunday's Marathon. Under the tunnel, up the hill to Sparrow rock. Lots of sparrows and in one berry tree a group of finches squabbling. There aren't enough berries for everyone? Robins gulp down berries whole. Finches are messy eaters, dig into each berry, toss off the parts they don't want, berry bits flying. I'd never seen them eat before. Berry-mush faces. Just like parrots and cardinals.
