I sit out on my front porch at least two hours a day; yes, I'm getting up in years. Other than bunches of smaller type trees, have a huge maple that provides me afternoon shade. I love watching the birds use a birdbath in the afternoon shade & also have a running fountain where the robins go wild bathing and cooling. Never have less than six pair nesting in the yard. Also have thrush,cardinals,redbirds,orioles,finch, mocking birds,warblers,finch, dove & about 4 breeds of sparrows and wrens. They all disappeared this week. Six days not a bird. The weather is in the low 80's. My neighbor lost ten chickens two nights ago, no remnants. Many big trees in neighborhood, hear many owls at night. Quit sure they are the chicken problem, are they mine also. Been here 15 yrs, have had the chicken problem before but no problem with the wild birds.
