The London Plane across the street was trimmed of its dead branches last week. Here’s the before… with the cherry-picker already scouting out the situation.
And after.
Over the years, we’ve seen these dead branches in action: as Kestrel perch and Kestrel prey cache; as crow raiding-site (see Kestrel cache); Red-bellied Woodpecker haunt (and again); and Blue Jay perch. It’s been a Northern Cardinal song stage and seen many a drama with House Sparrows, Mourning Doves, Common Grackles, Rock Pigeons, and European Starlings. A family of Eastern Kingbirds stopped by once. A Sharp-shinned Hawk tried to scare off the resident Kestrels.
Now, the tree is still here. After the trimming, a Tufted Titmouse was heard in there. There are just fewer places to perch and preen and sing out now.
Backyard and Beyond 
Perhaps yhere is a way to be a consultant to the tree -trimming bunch so that a balance is kept between trimming and leaving branches for wildlife.
