I watch critter encounters daily between our cat and birds at our window feeder. Case in point our cat and a Tree sparrow! The Tree Sparrow shows two identifying marks in the last photo: first identifying photo, a central breast spot and second identifying mark, the bottom yellow portion of its bicolour bill. The cat loves watching the birds up close and bats the window with its paw causing the bird top fly away, to return again!
