Description

Adults are 16–18 cm (6–8 in) long with short finch-like bills. They weigh about 1 ounce (28 g).[1] Adult males are mostly black, although they do display creamy napes, and white scapulars, lower backs and rumps. Adult females are mostly light brown, although their coloring includes black streaks on the back and flanks, and dark stripes on the head; their wings and tails are darker. The collective name for a group of bobolinks is a chain.[2]

Their breeding habitats are open grassy fields, especially hay fields, across North America. In high-quality habitats, males are often polygynous. Females lay 5 to 6 eggs in a cup-shaped nest, which is always situated on the ground and is usually well-hidden in dense vegetation. Both parents feed the young.

These birds migrate to Argentina, Bolivia and Paraguay. One bird was tracked flying 12,000 miles (19,000 km) over the course of the year, and up to 1,100 miles (1,800 km) in one day.[1]

They often migrate in flocks, feeding on cultivated grains and rice, which leads to them being considered a pest by farmers in some areas. Although Bobolinks migrate long distances, they have rarely been sighted in Europe—like many vagrants from the Americas, the overwhelming majority of records are from the British Isles.[citation needed]

Each fall, Bobolinks gather in large numbers in South American rice fields, where they are inclined to eat grain. This has earned them the name "ricebird" in these parts. However, they are called something entirely different in Jamaica (Butterbirds) where they are collected as food, being that they are very fat as they pass through on migration.

Bobolinks forage on, or near the ground, and mainly eat seeds and insects.

Males sing bright, bubbly songs in flight; these songs gave this species its common name.

The numbers of these birds are declining due to loss of habitat. In Vermont, a 75% decline was noted between 1966 to 2007.[1] Originally, they were found in tall grass prairie and other open areas with dense grass. Although hay fields are suitable nesting habitat, fields which are harvested early, or at multiple times, in a season may not allow sufficient time for young birds to fledge. This species increased in numbers when horses were the primary mode of transportation, requiring larger supplies of hay.

Media references

Emily Dickinson penned many poems about the bird, such as the following one:

The Bobolink is gone — The Rowdy of the Meadow —
And no one swaggers now but me —
The Presbyterian Birds can now resume the Meeting
He gaily interrupted that overflowing Day
When opening the Sabbath in their afflictive Way
He bowed to Heaven instead of Earth
And shouted Let us pray —

(The text follows R.W. Franklin's edition; the numbering is 1620 in Franklin's edition, while it is listed as 1591 in Thomas H. Johnson's.)

The bobolink is also mentioned in the song Evelina by Harold Arlen and Yip Harburg, from the musical Bloomer Girl:[3]

Evelina, won't ya ever take a shine to that moon?
Evelina, ain't ya bothered by the bobolink's tune?

The bobolink is also one of the many important ornithological references in Vladimir Nabokov's John Shade's poem "Pale Fire" in the novel of the same name:

But all at once it dawned on me that this
Was the real point, the contrapuntal theme;
Just this: not text, but texture; not the dream
But topsy-turvical coincidence,
Not flimsy nonsense, but a web of sense.
Yes! It sufficed that I in life could find
Some kind of link-and-bobolink, some kind
Of correlated pattern in the game,
Plexed artistry, and something of the same
Pleasure in it as they who played it found.

Sophia Jewett ends her poem "An Exile's Garden" (1910) with a reference to a bobolink:[4]

I live in the heart of a garden
With cypresses all about;
To the east and west, and the south and north,
Straight shadowy paths run out.
There are ancient gods in my garden;
They have faces young and pale;
And a hundred thousand roses here
Enrapture the nightingale.
Yet, among the gods of the garden,
The roses and gods, I think,
Daylong, of a far-off clover field,
And the song of a bob-o-link.
