Sandspurs, trash, birds

Interesting day.
It began with a routine work errand to remove sandspurs from the main path.
Along the way I watched a pair of American Kestrels seeming to have a dispute over the open territory that's probably a grasshopper bonanza for one of them.
When I reached the pines, I heard the Great Horned Owl calling. Breeding season is approaching for owls.
I looked down and saw a mound under the pine needles, I discovered a long-ago abandoned tire still on its rusty rim.
Nearby, I found more discarded stuff in a patch of saw palmetto .
It was quite a morning.
