I follow an eagle nest. There are two new little hatchlings and another due to hatch in another day. So if one of these two parents were to die, the other would have a real struggle to raise these three by him/her self. So this toll is not complete.
Not even close.
By now, there should be grackles carpeting every lawn in the area, sparrows and starlings, too.
Haven’t seen them in well over a decade.
The transient migratory birds who came through every spring fly at night, quite often, and the bird blenders get them.
Hardly any bird song in the woods.
*That* is the real “silent spring”.
