February and March are the most sensitive weeks of the year on your property. Not because of what you can see — because of what you can't.
Right now, Great Horned Owl chicks are already in nests. Gray squirrel babies are in tree cavities and sometimes in attics. Early cottontail litters are hidden in shallow grass depressions. Bald Eagles are incubating in the southern states. Red-tailed Hawks are sitting on first clutches. Great Blue Herons are repairing rookeries.
And on the ground, red foxes are scouting birthing dens. Coyotes are excavating. Raccoons are inspecting the lattice under your deck. Skunks are finding maternity sites. Most of these animals chose their spot weeks ago. They're already committed.
This is the window where a routine property task can destroy a nursery without you ever knowing it was there.
🪓 The chainsaw can wait
February and March are the worst time to prune large trees, remove dead snags, or clear heavy brush. A dead tree that looks like an eyesore may be an active nest site. If you see hawks or owls circling a specific tree or aggressively chasing crows away from it, that tree is being defended. It's occupied. Wait until late fall.
🏡 The shed and deck — inspect now, not later
If you have gaps under your shed, deck, or porch that you've been meaning to seal, check them with a flashlight this week. If the space is empty, seal it today with hardware cloth. If you wait until March, you risk trapping nursing mothers or newborns inside. The window between empty and occupied is narrow and it's closing right now.
🐾 What else helps:
- Keep dogs leashed near brush, tall grass, and den sites through March — free-roaming dogs are the primary cause of nursery failure for ground-nesting species
- If you find baby rabbits in a grass depression, leave them alone — the mother visits once a day for five minutes, and the nest is not abandoned
- If you find a baby squirrel on the ground, give the mother several hours to retrieve it before intervening — she usually does
- Delay any major landscaping, brush clearing, or tree work until late fall when nesting season is over
Spring doesn't start the clock on new life. It reveals the life that was already born in the cold 🌿
