What is the role of the Bobolink in the ecosystem?
When on the move, Bobolink flocks can eat large quantities of grains, and the birds are often shot as agricultural pests, particularly on their wintering grounds. Bobolinks are known as “butter birds” in Jamaica, where the plumped-up migrants are sometimes harvested for food as they pass through that country.
What is so striking about the Bobolink bird?
Perched on a grass stem or displaying in flight over a field, breeding male Bobolinks are striking. Added to this are the male’s rich, straw-colored patch on the head and his bubbling, virtuosic song. As summer ends he molts into a buff and brown female-like plumage.
What kind of bird is Bobolink?
blackbird
The bobolink (Dolichonyx oryzivorus) is a small New World blackbird and the only member of the genus Dolichonyx. An old name for this species is the “rice bird”, from its tendency to feed on cultivated grains.
Is the Bobolink endangered?
What is this species’ conservation status? 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.
What plants do bobolinks eat?
Majority of summer diet is insects, including beetles, grasshoppers, caterpillars, wasps, ants, and many others, also spiders and millipedes. Also eats many seeds of weeds, grasses, and grains. May feed more heavily on grain during migration, and in former times caused much damage in southern rice fields.
What does a bobolink bird 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.

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.
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.
Why is Bobolink endangered?
The main causes of the decline in Bobolink populations have been identified as: 1) incidental mortality from agricultural operations such as haying that destroy nests and kill adults, 2) habitat loss caused by the conversion of forage crops to intensive grain crops and other row crops, 3) habitat fragmentation, which …

What is the bobolink habitat?
Range: Originally found in tall-grass prairies and meadows, over the last century the Bobolink has adapted to farm croplands, such as hayfields and pastures. They can be found in southern Canada during their breeding season and have an extensive migratory pattern to South America.
What kind of life does a bobolink have?
Outside of the nesting season Bobolinks live socially in flocks. After arriving on the breeding grounds males compete vigorously for territories by singing, displaying, fighting, and chasing each other.
What do bobolinks do during their migration route?
During migration, bobolinks make long pit stops to eat in rice fields. Being diurnal foragers, they have night-time roosts along their migration routes. These birds have songs like a bubbly laugh, warbling with short notes over a wide pitch range. A soft “chuk” is their call, while the more musical flight call is a “bink” or “bwink”.
What can I do to help my Bobolink bird?
To improve the Bobolink’s prospects, people can maintain its breeding habitat by mowing fields annually once nestlings have fledged, and managing natural prairies through prescribed burning. Back to top If there’s breeding habitat of grassy pasture or overgrown fields near your home, Bobolinks may visit open yards to forage on seed-bearing weeds.
Why is the bobolink bird on the decline?
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.
