Our birds usually arrive in the last week of March or early April. Eggs are normally laid by the end of April. Chicks generally hatch late May or early June.
Chicks are sometimes ringed at approximately 5 weeks- early to mid July. Chicks fledge at about 7 weeks old- generally late July. The family stays at the nest until mid to late August.
The female leaves on migration first, often late July or early August. The male and chicks hang around our area until late August or early September but are seen at the nest less and less until they depart for the winter.
Why are eggs left unincubated for long periods of time? How long can the eggs be left alone? This depends on two things — predators and weather. Why does the female osprey fly off to eat elsewhere after receiving a fish? This behaviour is normal and very common in the period before the eggs are laid. Where does the male go overnight?

Also, in Florida and California some may migrate and others with decide to stay and enjoy our warm climate year round. Our American and Canadian Osprey, if they choose to migrate will usually winter in South America and then return home in the Spring.
In the springtime, when flowers are blooming, trees are beginning to exhibit signs of life these birds are beginning a 5 month courtship with their life mate to raise their young. The female will lay between 2 and 4 eggs that will be incubated for approximately 5 weeks.
When the chicks hatch they will weigh approximately 50 - 60g 1. The Osprey do not necessarily return to the same nest each year but they will reuse previously built nests.
Each season they will renovate previously built nests. When Osprey are underwater, they can close their nares, or nostrils, to prevent water from flowing in. If you have ever had water up your nose, you know how uncomfortable that can be. This is an important adaptation for a species that makes its living diving underwater.
If you look at an Ospreys' foot, you will see a few other interesting and important adaptations that help this fish-eating raptor catch its prey. The bottom of the bird's foot appears as though it could use some lotion, but what you are seeing are backward-facing barbs. These barbs make the Osprey's feet extra rough, which they need to be to hold on to a slippery fish. Another thing to notice is that two of the Osprey's toes face forward, while two face backward. They can change the position of their toes from this configuration to having three forward and one back.
This, too, helps these birds get a better grip on prey. Anyone who has tried to hold a slippery fish knows how easy it would be to drop one! Life is hard for any predator.
They must use a lot of energy when catching prey. If Osprey dropped many of the fish they caught, they would waste a lot of energy for nothing. These two adaptations help them hold on to their dinner as they fly to a secure perch to eat. Like so many other species of wildlife in the s and s, Osprey populations suffered negative effects from the widespread use of the pesticide DDT. Today, their populations are doing much better and Osprey seem to be holding their own. However, there are still many risks these beautiful birds of prey must face in their daily lives.
In some parts of the world, people shoot Osprey because they see them as competitors for the same food source. Contamination in rivers and lakes, loss of habitat, and even electrocution are some of the challenges facing Osprey in a modern world. Though Ospreys mainly eat live fish of a wide variety of species, the types of prey they might catch are quite diverse. Email Address: Follow. Follow me on Facebook.

The business end — the reversible toe in action to grip the branch Success stories such as the return of the osprey show what can be achieved when humans focus on the preservation of habitats and manage the use of chemicals that negatively impact habitats and infiltrate food chains.
