How do you tell long-billed dowitcher from short-billed dowitcher?

Do dowitchers have long bills?

Bill length, as expected, is one of the ID marks in the SurfBirds article above. Check out the 2 birds with an “A” by them. The one on the left has a much longer billl than the one on the right. Leg length is supposed to be another mark, with Long-billed Dowitchers having longer bills. Again check out the birds labeled “A”.

What is the difference between a dowitcher and a short-billed dowitcher?

In general, Long-billed dowitchers seem to prefer fresh over salt water and muddy over sandy habitats in comparison to Short-billed dowitchers. The long-billed dowitcher will migrate later in the fall than the short-billed dowitcher and earlier in the spring.

How can you tell if a bird is a long-billed dowitcher?

Leg length is supposed to be another mark, with Long-billed Dowitchers having longer bills. Again check out the birds labeled “A”. The one on the right has the water reach his belly, while the birds right around him have leg showing. Same for the one bird in the back by the “B”, where one bird has water reaching the belly, and the other two don’t.

Where do long-billed dowitchers live?

The Long-billed Dowitcher breeds in the high Arctic from eastern Siberia across Canada, and winters along both coasts of the United States and inland through Mexico and northern Central America. Description: This medium to large-sized shorebird has a bill that is twice as long as its head, and moderately long, pale legs.

What is a long-billed dowitcher?

Wintering flocks of Long-billed Dowitchers are muddy gray-brown birds that match their muddy foraging sites—a far cry from the intricate black, rufous, brown, and gold brocade of breeding birds on their tundra summer homes. These tubby, long-billed shorebirds plunge their bills deep into wet mud or sand to find invertebrate food.

What does a long-billed dowitcher eat?

Long-billed dowitcher. These birds forage by probing in shallow water or on wet mud. They mainly eat insects, mollusks, crustaceans and marine worms, but also eat some plant material. They are more likely to be seen near fresh water than the short-billed dowitcher .

How does a dowitcher find its prey?

The tip of a Long-billed Dowitcher’s bill has many tactile receptors called Herbst corpuscles that allow dowitchers to locate prey by touch. In 1950, Frank Pitelka was the first ornithologist to distinguish the Long-billed Dowitcher clearly from the three subspecies of Short-billed Dowitcher.

What do long-billed dowitchers eat?

Long-billed Dowitchers. Long-billed Dowitcher is a rare but regular visitor to western Europe, with some individuals staying for long periods. These birds forage by probing in shallow water or on wet mud. They mainly eat insects, mollusks, crustaceans and marine worms, but also eat some plant material.

What is the difference between male and female short-billed dowitchers?

Male Short-bills are easier to ID because of especially short bills and small, slender, compact bodies. It is the female Short-billed and male Long-billed Dowitchers that appear similar in size and structure. Short-billed has a bill that is thicker overall with a fairly blunt tip and a deeper base.

What does the long-billed dowitcher eat?

On the breeding grounds, Long-billed Dowitchers eat insects and insect larvae. On mudflats they also eat mollusks, crustaceans, marine worms, and other aquatic invertebrates.

What is the difference between a long billed and short billed dowitcher?

Long-billed Dowitchers are usually found in smaller flocks than Short-billeds, but huge flocks of Short-billed Dowitchers often include a few Long-billed Dowitchers. Long-billed Dowitchers feed by probing their long bills into mud or shallow water.

What do dowitchers eat in the ocean?

These birds forage by probing in shallow water or on wet mud. They mainly eat insects, mollusks, crustaceans and marine worms, but also eat some plant material. They are more likely to be seen near fresh water than the Short-billed Dowitcher.

What does a dowitcher sound like?

Long-billed Dowitchers feed by probing their long bills into mud or shallow water. Their bills are full of nerve endings, useful for sensing prey. They walk along slowly, lifting their heads up and down like a sewing machine. The call is a high peeping sound, usually a single call, but sometimes repeated.

What do dowitchers eat in Europe?

Long-billed dowitcher is a rare but regular visitor to western Europe, with some individuals staying for long periods. These birds forage by probing in shallow water or on wet mud. They mainly eat insects, mollusks, crustaceans and marine worms, but also eat some plant material.

How can you tell a dowitcher from a short billed dowitcher?

The Short-billed Dowitcher is very similar in appearance to the Long-billed Dowitcher. Both birds are large shorebirds. In breeding plumage, they are reddish underneath and mottled-brown above. In flight, they show a pale trailing edge on their wings and a distinctive white blaze up their backs, which easily identifies them as dowitchers.

How can you tell the difference between dowitchers and non-breeding birds?

Non-breeding plumage is very difficult to distinguish. Range, habitat, and vocalizations should all be used to help distinguish between these two species. During migration and winter, Short-billed Dowitchers are usually found in salt water on mud flats and tidal marshes.

What is the difference between a male and female short billed parakeet?

The female of both species has a longer bill than the male, and the bill of the female Short-billed is the same length of that of the male Long-billed, so bill length can be confusing. Short-billeds in breeding plumage usually have some spotting rather than barring on the sides of their breasts in front of the wings.

What is the difference between short-billed and long-B billed birds?

Other structural differences that have been mentioned in the literature include wing length and tarsi length (Pitelka, 1950). Pitelka showed that Long-billeds have slightly shorter wings but longer legs than all subspecies of Short-billed.
