Current Peregrine Falcon Situation
Have decreased from Endangered to Special Concern from the 1960s to 1999 due to human efforts
Today their estimated population is 2,000-3,000 nesting pairs
Peregrine falcons have been pulled back from the brink but humans need to continue to take the aforementioned measures to ensure the falcons stay this way
Why Save the Peregrines?
Keep small bird numbers in check
Used for hunting by falconers
Beautiful and majestic bird-ever since I saw one in my backyard I have been captivated by their beauty and grace
Should and can save the Peregrine Falcons
How Can Peregrine Falcons Be Saved?
Stop developing the cliff areas where they hunt and live for more housing
Don't use pesticides with chemicals like DDT and DDE which cause thousands of peregrine falcon eggs to go unhatched every year
Why are they Endangered?
During World War II, many peregrine falcons were shot down in England because they preyed on carrier pigeons
More and more houses were built on cliffs overlooking water and open spaces where Peregrine Falcons live and hunt because few hiding spots for prey
Biggest problem is DDT and DDE in pesticides
DDT and DDE cause the eggs to break before they can hatch
Peregrine Falcons only breed once a year, laying 3-4 eggs so losing their offspring for a year is devastating
Mate for life and are k-strategiest so hard for them to recover from the detrimental human effects
Role in Ecosystem
Peregrine falcons are near the top of their food chain, feeding on other bird species as well as bats
Fledgling peregrines are occasionally killed by great-horned owls and golden eagles and eggs are eaten by raccoons but once the falcons are full grown, nothing preys on them
Not a keystone species but they do ensure the small bird populations are kept in check
Only real threat to these birds are humans and their harmful practices
Peregrines in Trouble
In the 1960s, Peregrine Falcon numbers dipped until there were no nesting pairs in North America
Bred in captivity and 3,400 falcons were released in North America
Not permanent solution to the problem
In order to stop the rapid drop in numbers, we must know what pushed the Peregrines to the brink
Lives up to 17 years old
14-19 inch body and a 3.3-3.6 foot wingspan
Can weigh anywhere from 18.8-56.5 ounces
Adaptable and able to survive in most environments so unaffected by climate change
Only limited by extreme elevation or temperature
Should not be in danger-but are because of human factors
Flies up to 200 miles per hour
Lives on every continent except Antarctica
Preys on other bats and birds while in flight
Name itself means wanderer. Will travel up to 15,500 miles for a suitable spot outside of nesting season but has homing instinct that leads them back
Generations of peregrine falcons use the same nesting sites for hundred of years
Part of the Falconidae family
Bird of prey like other falcons, hawks and eagles
