This is again from Whipsnade wildlife park. I never noticed the brave raven flying above the eagle until I checked the shots.

This is a Bald Eagle, one of a pair at Whipsnade wildlife park. This eagle named "Apache" was part of the bird display, which is a very popular show at the park.

Some facts

Scientific name - Haliaeetus leucocephalus

There are two subspecies of bald eagles. The "southern" bald eagle, Haliaeetus leucocephalus leucocephalus, is found in the gulf states from Texas and Baja California across to South Carolina and Florida, south of 40 degrees north latitude. The "northern" bald eagle, Haliaeetus leucocephalus alascanus, is found north of 40 degrees north latitude across the entire continent. The largest number of northern bald eagles are in the Northwest, especially in Alaska. The "northern" bald eagle is slightly larger than the "southern" bald eagle.

Both male and female adult bald eagles have a blackish-brown back and breast; a white head, neck, and tail; and yellow feet and bill.

Juvenile bald eagles are a mixture of brown and white; with a black bill in young birds. The adult plumage develops when they're sexually mature, at about 4 or 5 years of age.

Size - The female bald eagle is 35 to 37 inches, slightly larger than the male. With a wingspan which varies from 79 to 90 inches.

The male bald eagle has a body length from 30 to 34 inches. The wingspan ranges from 72 to 85 inches.

Voice - Shrill, high pitched, and twittering are common descriptions used for bald eagle vocalizations. Eagles do not have vocal cords. Sound is produced in the syrinx, a bony chamber located where the trachea divides to go to the lungs. Bald eagle calls may be a way of reinforcing the bond between the male and female, and to warn other eagles and predators that an area is defended.

Skeleton - It weighs about half a pound (250 to 300 grams), and is only 5 or 6 percent of its total weight. The feathers weigh twice that much. Eagle bones are light, because they are hollow. The beak, talons, and feathers are made of keratin.

Respiratory system - Eagles have external nares opening on both sides of the bill. A bald eagle never reaches speeds that would interfere with normal breathing. The eagle's lungs and air sac system is adequate for its size. Air moves in through the lungs and on into the air sacs before moving back through the lungs and out again. Air passes through the lungs twice with each breathing cycle - twice that of mammals. More about the respiratory system of birds

The beak and talons grow continuously, because they are made of keratin, the same substance as our hair and fingernails. The beak of a captive eagle is not warn down naturally, so must be trimmed annually.

Excelent capture of the bald eagle in flight.
This is a good example showing the size of the eagle to the raven. Well done on this composition. Good eye.

Nice capture Alan. I think the inclusion of the crow gives it a little extra and is good value for money! Nice detailed flight shot, the lighting is nice too giving detail under the wings. Good work.

Alan, A unique capture with the other bird above..Reminds me of the jets at LAX in holding patterns waiting to land! ;-)) Well composed with good sharpness and details. I think the clouds low-rt help the shot also. Great job on this!

Alan, simply wonderful. I'm impressed about this photo. How I do enjoy the flights/poses.

It's a privilege to take a shot like this.

Congratulations.

This is an amazing shot... Having both birds in the picture. Any idea how they were ?

colours are good, you can see the details on the wings as well.

Hi Alan, this is great! The Raven flying above the Eagle is a real bonus and gives this picture something extra. It does seem like he;s imitating his biggger brother. :) Wonderful! Composition is excellent. Great note aswell. Well done & TFS!

Excellent shot Alan. Good action with both birds in the frame. Well done on this superb capture. TFS
