Ospreys, or "Fish Eagles", Pandion haliaetus, are fairly common along shorelines, marshes, and larger inland waterways. They dive for fish, catching them with their talons - which is quite a sight to see. At the last moment in its headlong plunge, the bird pivots to strike the water feet-first.

At 22", wingspan 54", Ospreys are smaller than eagles, but larger than hawks, and form their own family. Once threatened by DDT, which thins the shells of their eggs and makes them susceptible to breakage, Ospreys have made a great comeback and may be seen around almost any salt marsh. They nest in trees, or on special platforms that are erected for them. Several nesting pairs of Bald Eagles also live in the region.

Bald Eagles, much larger than Ospreys, with an all-white head and neck, are making a recovery. Don't be too surprised to see one!

Surprisingly, of all the devices that make up an underwater diving kit, the last to be developed was a suitable air reservoir. Demand air valves ( regulators to you and me, ) masks, fins, snorkels, weights, even drysuits may be found in the historical record up to several hundred years ago, but because of material and manufacturing requirements, the high-capacity high-pressure portable air cylinder is a relatively recent development. ( Jacques Cousteau often gets credit for something he did not invent - the demand-valve regulator predates him considerably, although he did much to perfect its application to diving. )

2016 Update

Litigation has caused manufacturers to leave the market, and be replaced by others, who then left, and then others come back. From year to year, there's no telling what brand of tanks may be available, but the specs and recommendations below should apply to any.
