Roles within community: There are no community roles they barley interact with each other
Male Or Female Led groups: There is no group leader and they dont form permanent groups
Individuals that make up the group: They only pair up for mating
Interaction: They are territoral during breeding but they can tolerate others during migration
Mating frequency: Once a year
Number of mates: Monogamous during the breeding season
mating season: Late spring to early summer
Mating rituals: males preform displays and calls to attract females
Number of Offspring produced at a time: 1-4 Eggs
Unique characteristics: Both parents help building the nest and raising the chicks
Stages of development:
Egg Stage: Incubation lasts 28-31 days
Nesting Stage: chick remains in nest for 35-42 days
Fledgling Stage: Young hawks learn how to fly and hunt before leaving the nest

Causes Of Death
Predation- Young hawks and eggs are preyed by raccoons, owls, and other raptors
Sexual competition- A rare cause of death close to none
Disease- Avian diseases like west nile virus
Competition
Inter species- Compete with other birds of prey like red tailed hawks for food and territory
Intra species- Complete for nesting sites and food
What do they compete over?- Small mammals, reptiles, insects, and territory
Effects of invasive species- invasive predators and habitat
loss caused by invasive plants can limit nesting areas and food
IUCN
Rating: Listed as Least Concern
Population: estimated at 1.8 million
Population Trend: Stable
Impact Of Humans
Past Impacts: Habitat damage due to deforestation and urbanization. Also the use of pesticide affects reproduction.
Potential Future Impacts: Climate change can disrupt migration or food availability. Also deforestation.
Human Interaction Timeline: Humans have been impacting their habitats for a long time due to agriculture expansion and logging
Efforts Made To Minimize Impacts:
-Conservation of forests and wetland habitats
-Laws protecting the bird
