Ospreys, commonly seen
flying above shallow inland waterways or near the sea, are one
of the few birds of prey that subsist almost exclusively on
fish. Most Ospreys are migratory, traveling from northern
breeding grounds to winter locales near tropical lakes, rivers,
seashores and coral reefs. Ospreys have some of the widest
habitat range of any raptor species and can be found on every
continent except for Antarctica. Osprey populations have
rebounded significantly following the ban on the pesticide DDT,
representing one of the most successful environmental
conservation stories in North American history.
Ospreys usually mate for life and nesting pairs return to the
same nest every year to lay eggs. Some Osprey nests span many
generations and can be over 70 years old. Ospreys typically
situate their nests close to shallow bodies of water, often atop
snags (standing dead trees) or man-made structures like
telephone poles or platforms constructed specifically for Osprey
nests. Osprey eggs have an incubation period of about 5 weeks.
New hatchling(s) typically have their first flight after 8 to 10
weeks of living in the nest. While the female is carrying and
sitting on the eggs, the male Osprey may catch fish and bring
them to the female.
