Get To Know This Yr’s Featured World Migratory Hen Day Species: Osprey


Very important Indicators

Frequent title: Osprey

Vary: Throughout the summer season months, the osprey’s breeding grounds span elements of Alaska and the northern United States, in addition to all Canadian provinces and territories apart from Nunavut. When fall arrives, they migrate in the direction of the coasts of the southern United States and Mexico, in addition to the higher half of South America.1
Common Lifespan: 15 to 25 years2
Measurement: Size of 54 to 58 cm with a wingspan of 150 to 180 cm, sometimes weighs 1400 to 2000 g2
Inhabitants estimate: 50,000 to 500,000 in Canada1

The Information

The osprey is a comparatively giant hawk that lives and hunts round water. The osprey has a mixture of white and brown feathers, the underside of its physique and wings are principally white, with a number of brown spots, and the highest of its wings are principally brown. Female and male ospreys search for essentially the most half an identical, with the smaller dimension of the females being essentially the most noticeable distinction.2

The osprey is well-known for its potential to catch fish. They are going to circle a physique of water searching for a fish to catch, then will dive within the water and seize it with its claws. The osprey is quite distinctive in having a reversible outer toe that it makes use of to grip and safe its prey because it emerges from the water. Their dives are often profitable 25 to 70% of the time, and they also eat nearly solely stay fish.2

Whereas more often than not they nest on prime of a giant tree, they’ll usually make their nests on synthetic buildings like utility poles or duck blinds. In each circumstances, they’ll select to make their nest excessive up in a big open space close to water. The feminine will lay just one brood of two to 4 eggs per 12 months that takes, on common, 38 days to hatch. As soon as hatched, the younger osprey learns to fly after about 51 to 54 days.3

The Story

The osprey is taken into account to be a species at low danger of changing into endangered in Canada. Like many water loving birds, they confronted a serious decline of their numbers within the Nineteen Fifties to Nineteen Seventies as a result of widespread use of dangerous pesticides equivalent to DDT. As well as, they’ve traditionally been at a excessive danger of being shot whereas at their wintering grounds in South America. Ospreys usually hunt at aquaculture services in South America and have usually been shot by employees making an attempt to guard their fish. Right now the rules for looking ospreys are a lot stricter, and that, mixed with the restrictions on dangerous pesticide use, has led to a 200% improve in Osprey numbers in Canada for the reason that Nineteen Seventies. Primarily based on the Breeding Birds Survey, there are as we speak an estimated 50,000 to 500,000 people in Canada.1

What you are able to do

Even supposing their inhabitants is at present steady in Canada, the osprey is liable to seeing a decline of their inhabitants dimension primarily as a consequence of habitat loss and local weather change. Like many various species of waterfowl, threats to aquatic ecosystems like droughts and water air pollution can negatively have an effect on fish populations, their major meals supply, and in flip result in a lower of their osprey numbers. As well as, with many giant bushes having been minimize down, the osprey is changing into more and more reliant on synthetic buildings to make their nests. Sadly, grownup ospreys generally incorporate completely different plastics of their nest that may find yourself wrapping round a chick’s foot and injure it. As a consequence of this, they’re one of many species which are most affected by plastic air pollution. With that being mentioned, Canada has recognized the osprey as a precedence for conservation and stewardship methods within the hopes of sustaining their present numbers.1

All issues thought of, advocating for the conservation of wetlands in Canada, a discount in single use plastics, and conserving nature, basically, are nice methods you’ll be able to assist to help the osprey.

It’s also possible to become involved with an area Hen Staff in your neighborhood to work in the direction of changing into Hen Pleasant Metropolis Licensed or host and take part in an upcoming World Migratory Hen Day occasion close to you! It’s also possible to contact your Metropolis Council and urge them to hitch cities like Vaughan, Barrie, and Vancouver, to proclaim their help of World Migratory Hen Day.
