Bird Behavior and Diet
Most birds eat seeds, nectar, insects and their larvae, aquatic animals, and sometimes carrion. They have no teeth and use their beaks to break food into smaller pieces for swallowing. Birds in New York, New Jersey, and Connecticut are scavengers, feeding on whatever they can find, dead or alive, in urban and rural locations.
Many nuisance species are social and gather in flocks to feed and breed, increasing the negative impact on properties and commercial areas. Birds forage and congregate around dumpsters, loading docks, outdoor dining, and landscaped areas. Most remain close to nesting sites to limit travel, so bird infestations often remain in place for some time.
Bird Reproduction and Life Cycle
Most birds mate after prolonged courtship rituals that can include calls, elaborate displays, or shared feeding. The female bird may lay her fertilized eggs a few days after mating or may wait several months, depending on the species. After laying her eggs, the mother protects and incubates them with her body until they hatch, between ten days to three weeks later.
Birds pass through several stages of development before reaching adulthood:
- Hatchlings: Recently hatched and fully dependent on parents.
- Nestlings: Remain in the nest, unable to feed or care for themselves.
- Fledglings: Grow feathers and begin learning to fly.
- Adults: Capable of flight, seeking mates, and building nests.
