Happy Osprey Day!


Happy Osprey Day!

On Mother’s Day, we took a trip to the Edwin B. Forsythe National Wildlife Refuge in New Jersey. This is the kind of gift I love, to be out in natural settings, observing animals and birds in their native habitats.

One particular thing I observed that day was the scattering of osprey nests through the refuge. In the wild, the male osprey gathers the makings of the outside of the nest - twigs, sticks and branches - and the female lines it with grass, sod, vines, and sometimes found materials. They like to build their nests in open spaces, usually near a water source as they tend to eat fish exclusively, leading to their description as fish hawks. The problem is that ospreys may build nests on man-made structures such as telephone poles, utility poles, buildings, and other open spaces, which can pose a hazard for the birds. This was not the only hazard. Ospreys became endangered as a result of DDT spraying, before the chemical was banned in 1972. They have recently been rebounding, partly due to the support of wildlife and conservation organizations. They often construct platforms for ospreys to nest on, in protected areas out of harm’s way.

This day, we saw lots of ospreys perching alongside the nests. I wondered if they were the males or females as both tend to the nestlings. On this special day, I chose to imagine they were the mother birds, watching over their babies. Mothers, regardless of category, have much in common. I sent them silent messages of appreciation and understanding; raising youngsters is an all-consuming job (Can you see the baby in the nest?). I was glad that the adults were being cared for, too, by the wildlife conservation community. We need to support each other. It is cause for celebration when we can say that a species is reclaiming its right to exist.

Happy Osprey Day!

Bald Eagles are Back!


Bald Eagles are Back!

I see many birds in my backyard, even some large ones like crows, hawks, ducks and the occasional turkey vulture. Bald eagles, however, are not among them. This weekend I took a mini-cruise on the Maurice River in NJ and had the opportunity to spot eagles galore. Some were on their nests, others were perched on the bare wood of trees along the banks of the river. The eagle here (click on the photo to enlarge it) had caught a fish and was flying off with it. The bird landed on a branch and proceeded to enjoy its meal.

The bald eagle, our national symbol, was once in trouble. A combination of land development, destroyed habitat, and hunting threatened to destroy the eagle population. Some claimed that the pesticides like DDT were responsible for thinning the birds’ eggshells and contaminating fish and water supplies. The population had gone from 100,000 nesting pairs to only 487 in 1963. DDT was banned in 1972 and on July 4, 1976, the US Fish and Wildlife Service officially listed the bald eagle as a national endangered species.

Since then the eagle population has rebounded. On June 28, 2007, the Department of the Interior announced the recovery of our nation’s symbol and removal from the list of threatened and endangered species. There are now over 9,700 nesting pairs in the U.S. Quite a comeback.

Seeing a bald eagle is thrilling. It has a presence. It also has a right to be here, as much as we do. We really do need to be more sensitive to our world. I’m glad to see the bald eagles are back.
