Ospreys typically start their breeding season in early spring, with pairs arriving at their established nest sites. They are monogamous and often return to the same nest year after year, though males may arrive before females. Courtship and nest building or repair commence after a pair reunites. The female lays between two and four eggs, which are incubated for around 38-42 days.
Breeding Season and Timing:
Arrival:
Ospreys arrive at their breeding grounds in late March or early April, with males often arriving slightly earlier.
Courtship:
Courtship displays include aerial displays, known as "sky dances," where males fly high and dive near the nest site, sometimes carrying a fish or nest material.
Nest Building/Repair:
Pairs work together to build or repair their large, bulky nests using sticks, branches, and other materials.
Egg Laying:
The female typically lays one to four eggs in a clutch. Eggs are usually laid in a series, over a few days.
Incubation:
Both parents share incubation responsibilities, with the female often doing more.
Hatching:
Eggs typically hatch after about 35-40 days.
Fledging:
Chicks learn to fly and fish after about two months, and remain in the nest for another two months, receiving parental care and continuing to learn hunting skills.
Key Characteristics:
Monogamous: Ospreys are generally monogamous and often pair for life.
Nest Reuse: They often return to the same nest site year after year.
Parental Care: Both parents care for the young, with the male primarily bringing fish and the female brooding and feeding the chicks.
Nest Location: Nests are typically built on large trees, utility poles, or man-made structures near bodies of water.
