Why are Bobolinks endangered?
The bobolink is assessed as threatened in Canada by the Committee of the Status of Endangered Wildlife in Canada and listed under the Species at Risk Act. Bobolink populations are declining because of the loss of prairies and other grasslands habitats. Habitat loss and fragmentation is the key threat for this species.
How many Bobolinks are left?
Species Status Statement. These birds migrate to southern South America during the non-breeding season, in one of the longest migrations known for songbirds (Renfrew et al. 2015, eBird 2019). The global population of bobolink is estimated at 10 million, with 7.6 million in the U.S. (Partners in Flight 2019a).
Are Bobolinks extinct?
Once common in hayfields throughout the Northeast, Bobolinks have been in decline since the 1900s. Their decline is hastened by the intensification of farming practices: many fields are now being mowed earlier and more frequently than they were in the past.
Why are Bobolinks called Bobolinks?
Etymology. The genus name Dolichonyx is from Ancient Greek dolikhos, “long”, and onux, “claw”. The specific oryzivorus is from Latin oryza, “rice”, and vorare, “to devour”; an old name for this species is “Rice Bird”. The English “Bobolink” is from Bob o’ Lincoln, describing the call.
Where do Bobolinks nest?
Original prime breeding areas were damp meadows and natural prairies with dense growth of grass and weeds and a few low bushes. Such habitats still favored but hard to find, and today most Bobolinks in eastern United States nest in hayfields. Migrants stop over in fields and marshes, often feeding in rice fields.
How many Bobolinks are in Canada?
1.8 and 2.2 million breeding
In Canada, the Bobolink population is estimated at between 1.8 and 2.2 million breeding birds.
What are Bobolinks predators?
Ground based nests are very vulnerable to predators. Many of the “usual suspects” of egg and nestling predators affect bobolink nests (including skunks, raccoons, foxes, and snakes). A surprising bobolink nestling predator is the white-tailed deer.
What does a Bobolink look like?
Breeding male Bobolinks are mostly black with a white back and rump, and a rich buffy nape. Females and nonbreeding males are warm buffy brown, streaked with dark brown on the back and flanks. They have bold brown stripes on the crown but are unstreaked on the nape of the neck. The bill is pinkish.
Where do Bobolinks go in the winter?
Most Bobolinks winter east of the Andes in the grasslands (or pampas) of southwestern Brazil, Paraguay, northern Argentina, and central Bolivia. Geolocator data revealed that Bobolinks often pause for several weeks in the grasslands of Venezuela, Colombia, or Bolivia before continuing on to wintering areas.
Where do Bobolinks overwinter?
How many Bobolinks are in the world?
Population. The population is healthy as of 2021. It is estimated to be around 9.7 million birds, and the conservation status is the least concern. Yet the numbers are declining and the bird’s Canadian population might become of concern in the future.
What are bobolinks predators?
Is the bobolink protected under the species at Risk Act?
The Bobolink is protected under the federal Species at Risk Act (SARA). More information about SARA, including how it protects individual species, is available in the Species at Risk Act: A Guide.
Why did the bobolink go extinct?
People have shot Bobolinks as agricultural pests in the southern United States, trapped and sold them as pets in Argentina, and collected them as food in Jamaica. But the main reason for the Bobolink’s decline is land-use change, especially the loss of meadows and hay fields.
What does a bobolink bird look like?
The Bobolink is a medium-sized passerine. Males are black below and lighter above, while females are light beige streaked with brown and could be mistaken for some species of sparrow. The Bobolink has a conical bill, rigid, sharply pointed tail feathers and long hind toenails.
Is the bobolink polygamous?
The Bobolink is a semi-colonial species that is often polygamous, depending on the region and habitat conditions. The first adults arrive from their wintering grounds in mid-May. Upon arrival on the breeding grounds, the males establish their territories, performing courtship flights and songs.
