The Osprey


The Osprey (Pandion haliaetus), sometimes known as the sea hawk, is a diurnal, fish-eating bird of prey. It is a large raptor, reaching 60 centimetres (24 in) in length with a 2m wingspan. It is brown on the upperparts and predominantly greyish on the head and underparts, with a black eye patch and wings.The Osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica although in South America it occurs only as a non-breeding migrant.

As its other common name suggests, the Osprey's diet consists almost exclusively of fish. It has evolved specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. Despite its propensity to nest near water, the Osprey is not a sea-eagle.
The Osprey differs in several respects from other diurnal birds of prey. Its toes are of equal length, its tarsi are reticulate, and its talons are rounded, rather than grooved. The Osprey and Owls are the only raptors whose outer toe is reversible, allowing them to grasp their prey with two toes in front and two behind. This is particularly helpful when they grab slippery fish.

The sexes appear fairly similar, but the adult male can be distinguished from the female by its slimmer body and narrower wings. The breast band of the male is also weaker than that of the female, or is non-existent, and the underwing coverts of the male are more uniformly pale. This is a good guide to determine the sex in a breeding pair, but harder with individual birds.

The Osprey breeds by freshwater lakes, and sometimes on coastal brackish waters. Ospreys usually mate for life.
All these photographs were taken in various locations in Florida where they are extremely abundant due to a great effort to build back up the population. Like eagles, they suffed a big drop in their population from the use of pesticides that worked there way into the food chain.They have rebounded well and now can easily be observed in great numbers.

J. N. "Ding" Darling National Wildlife Refuge



There are countless amazing locations to photograph wildlife in Florida. There are dozens of books and publications that cover everything you would want to know on the subject. I regularly visit one of the top rated bird photography spots in the country. It is located on Sanibel Island, off the coast of Ft. Myers. J.N. "Ding" Darling National Wildlife Refuge is a bird photographer’s paradise. I have made the trip to this place at least once or twice a year for the past five years. I usually spend several days photographing the diverse bird population that can be found there.






 
 
 
 
One of the big attractions at the refuge is the large colony of American White Pelicans that come to winter and start their breeding season. It is fun to watch these large birds come crusing in for a landing in the shallow waters to feed or rest. They are a good target to practice your in-flight photography skills on as they are very large and do not move erratically like many birds do. They will winter as far north as the St. Louis area. You can see them in the Riverlands Wetland Area over in West Alton.
 

Another favorite target of mine is the numerous Ospreys that are found in the refuge. The Osprey (Pandion haliaetus), sometimes known as the sea hawk, is large raptor reaching 24 inches in length with a 5-6 foot wing span. It is brown on the upperparts and predominantly greyish on the head and underparts, with a black eye patch and wings. Fish make up 99% of their diet. They are efficent hunters and have hugh curved talons for grabbing fish just below the surface of the water.


This photo is of a Female Common Merganser Duck. The long, narrow bill with serrated edges readily distinguishes mergansers from all other ducks. Common mergansers are among the largest ducks, but are less stocky than eiders and goldeneyes. In flight, they appear more elongated than other ducks, flying in trailing lines close to the water's surface. Male common mergansers have a greenish-black crested head and upper neck. The lower neck, breast and underparts are creamy-white with a variable pink wash. They have black backs and upperwing coverts with white scapulars. The bill is red with a blackish culmen and nail. The legs and feet are a deep red. Female common mergansers have a tufted red-brown head that is clearly defined from the lower neck by a clear whitish chin. The back and sides are silver-gray and the breast and belly are white. The bill is red with a blackish culmen and nail. The legs and feet are deep red.



Although the weather has been less than ideal for my entire week in Florida, It was still better here than in St. Louis. But the sun has set on my final day here and I will be returning home on Saturday.

Have a great weekend.

Sanibel Island Photography

Thick clouds, cold temperatures, and a stiff wind do not make for good conditions to do bird photography in a sub-tropical climate. Upon my arrival at Ding Darling National Wildlife Refuge, there were only a few birds around. Most were sittting far back in the trees trying to stay warm. There did not appear to be any signs of a break in the clouds so I did what any good photographer would do. I went to breakfast. Then I took my wife shopping. While keeping my eye on the skies, I saw a few breaks in the clouds. My wife was nice enough to keep shopping and allow me to head back to the refuge.


Small pockets of sunlight started peeking through breaks in the clouds. Although there was not much to photograph, I was able to spot this Great Blue Heron perched on a log.  He was sitting back in a dark spot, but had some sunlight shining on him. I spot metered on the heron and it allowed the background to go completely black. I think it makes for a dramatic photograph. But then it clouded up again and the photography was on hold for a while.



Finally late in the day the skies cleared and I was able to start looking for something to focus that 800mm lens on. I headed to the south end of the island by the lighthouse. There is a nesting pair of Osprey that have been there for a few years using the same nest. I pulled into the parking lot and was setting up when this Osprey landed in the tree right over my head. (My luck was finally improving) It appears that fresh Flounder was on his menu as he started to feed. I actually had to back up across the parking lot to get him all in the frame.  (How rare is that when you have to back up instead of trying to get closer) He kept having to flare his wings to keep his balance as the wind was still blowing pretty hard.   



With the sun quickly going down and clouds starting build, I headed out onto the beach to try some shorebird photography. To be honest, I do not know exactly what species of shorebird this is, but I think it is a Black Bellied Plover, but I will have to ID it when I get home. There was a nice soft light at this point, and I was able to get a few photographs. There were a lot of people on the beach and it became to difficult to do any photography, so I called it a day. I wanted to get a nice sunset, but off shore clouds were moving in. So I have posted a nice sunset I did from Blind Pass Beach that I did last year at this time.

  

Have a great day
