Here are the original photos:
Challenge 1: Red Tailed Hawk. It just finished eating a vole and looked at me sheepishly.
Challenge 2: Snowy Owl as it came on to land in one of the trees by the paved road. It was flying between the slope of the nearby hill and a group of trees on another hill across the street. Had great fun watching it while it lasted.
Challenge 3: Northern Shrike. it has been around the park for a while and seen quite frequently.
Challenge 4: American Pipit. It was a cold and windy November day when I spotted a group of them foraging on the ground.
Challenge 5: Northern Flickr as they were searching for a nesting hole. I think eventually they were evicted by the Starlings.
Challenge 6: Field Sparrow
Challenge 7: American Kestrel on a very windy day
Challenge 8: Turkey Vulture
Challenge 9: White-throated Sparrow
Challenge 10: Pied-billed Grebe
