One of the reasons for that may be this from Observer:
However, the FWS has not found any dead birds or other wildlife in the natural habitat near the launch site. The area surrounding Starbase is part of a National Wildlife Refuge property, where some endangered species of migratory birds, including piping plover, come for nesting each spring. Before last week’s launch, biologists had already noticed a decline in nesting activities in the area since SpaceX began regularly testing Starship prototypes in 2020.
