Do not trim your trees or shrubs during nesting season - between April and August. Babies are hatching during this time and you could injure or kill them. Birds can also nest in tall grass so be careful if you use a bush hog or weedeater. Avoid pesticides between April and August. Remember, some mole cricket eradicators also kill many birds when they eat the poisoned insects.
Some rat poisons can kill owls, hawks, eagles and also cats who eat the poisoned rat.
It is a gruesome sight to see a Great Horned Owl die by Poisoning. A pelican was found dangling in fishline from a tree on the beach. A tern was found floating down river with its wings caught in a plastic grocery bag. The bag was filling with water and the bird almost drowned. A gull was starving because of a plastic six-pack ring around its neck.
