How high can a thick-billed murre fly?

What is a thick-billed murre’s nest like?

The Thick-billed Murre’s nest is a rough pile of pebbles or other debris, often cemented in place by the birds’ poop. The resulting structure may help to keep the egg from rolling off ledge if it is dislodged. The Thick-billed Murre does not breed until about the age of 4 years. Year-old birds remain at sea and don’t visit nesting areas at all.

How fast can a murre bird fly?

Takeoff is awkward, but once it’s airborne, the thick-billed murre can fly at about 75 miles an hour. Among the deepest underwater divers of all birds, it uses its stubby wings to “fly” through the water, routinely reaching depths of more than 330 feet—sometimes even twice that—in pursuit of the fish, squid, and crustaceans it feeds on.

What kind of bird is a thick-billed murre?

How does a murre bird leave the nest?

Young Thick-billed Murres leave the nest cliff while still flightless and only about a fourth the size of an adult. Encouraged by their father, they take a seemingly death-defying leap off their nest ledge and use their tiny, undeveloped wings to glide and flutter downward.

Male and female are indistinguishable in the field and weight ranges between 945 g (2 lb 1 1⁄2 oz) in the south of their range to 1,044 g (2 lb 5 oz) in the north. A weight range of 775–1,250 g (1 lb 11 1⁄2 oz–2 lb 12 oz) has been reported.

What is the difference between a murre and a bill?

Thick-billed Murre – eBird Black-and-white seabird; breeds in colonies on rocky islands and cliffs. Spends the rest of the year on the ocean, when it is seldom seen from land. Bill is shorter and thicker than Common Murre, but difficult to judge at a distance. Note blacker plumage, cleaner sides, and limited amount of white on throat in winter.

How deep can a murre fish dive?

Common murres have fast direct flight but are not very agile. They are more maneuverable underwater, typically diving to depths of 30–60 m (100–195 ft). Depths of up to 180 m (590 ft) have been recorded.

How deep can a bird fly underwater?

How long can a murre swim underwater?

The common murre is a pursuit-diver that forages for food by swimming underwater using its wings for propulsion. Dives usually last less than one minute, but the bird swims underwater for distances of over 30 m (100 ft) on a regular basis. Diving depths up to 180 m (590 ft) have been recorded and birds can remain underwater for a couple of minutes.

How long do murres stay in the nest after breeding?

Chicks are capable of diving as soon as they hit the water. The female stays at the nest site for some 14 days after the chick has left. Both male and female common murres moult after breeding and become flightless for 1–2 months. In some populations they occasionally return to the nest site throughout the winter.

What is another name for a thick-billed murre?

The very deeply black North Pacific subspecies Uria lomvia arra is also called Pallas’ murre after its describer.

How does the thick-billed murre fly?

The thick-billed murre’s flight is strong and direct, and they have fast wing beats due to the short wings. Like the other auks, these birds forage for food by using their wings to ‘swim’ underwater.

Where do murres make their nests?

The common murre nests in densely packed colonies (known as “loomeries”), with up to twenty pairs occupying one square metre at peak season. Common murres do not make nests and lay their eggs on bare rock ledges, under rocks, or the ground.

What is a scrape nest made of?

Scrape Nests. The scrape nest represents the simplest type of nest that a bird can build. It’s typically just a scrape in the ground that makes a shallow depression for the birds to lay their eggs. The rim of a scrape nest is just deep enough to keep the eggs from rolling away. Some birds may add stones, feathers, shells, or leaves to the scrape.
