Nyjer seed

Nyjer, a small black seed, is favored by goldfinches and other finches for its size and high oil content. But what is it, and where does it come from?

The seed is sometimes called "thistle," but actually it's not related at all to the pink- or purple-flowering thistle weed sometimes found locally. Nyjer, pronounced "NYE-jerr," is the seed of the yellow flower of the Guizotia abyssinica plant.

Nyjer is an oil seed crop that is cultivated in Burma, India, Nepal and Ethiopia. The plant is 4 feet tall on average but can grow as high as 7 feet under the right conditions. It is harvested while the flower buds are still yellow, then stacked to dry. The seeds, loosely held in the flower head, are black, club-shaped and narrow.

It is the only major wild bird feed imported from overseas. It's been marketed for wild bird seed for about 40 years. In 1985, the U.S. Department of Agriculture ruled that the seed must be heat-treated as a condition for entry into this country. In 1997, the treatment temperature was set at 250 degrees for 15 minutes to "devitalize" any weed seeds present. As a result, Nyjer will not sprout on lawns beneath bird feeders. But the finches still love it!

Killdeer

A shorebird that you can see without going to the beach, Killdeer are plovers commonly found locally on lawns, golf courses, athletic fields or parking lots. The tawny colored birds have the characteristic large round head, large eyes and short bill of all plovers. They are slender and lanky with long pointed tails and long wings.

Killdeer in its urban habitat
Killdeer are brownish tan on the top and white below. The white chest is barred with two black bands, and the brown face is marked with black and white patches. The bright orange rump is conspicuous in flight.

Typically you can see these birds running across the ground in spurts, quickly stopping to check their progress or to see if they startled any insect prey. Near the shore, they inhabit open areas such as sandbars, mud flats and grazed fields.

Killdeer feed primarily on invertebrates such as earthworms, snails, crayfish, grasshoppers, beetles and aquatic insect larvae. They also follow farmer's plows looking for unearthed worms or insect larvae.

Killdeer nest; note the speckled eggs
The nest of the Killdeer is a shallow depression scratched into the bare ground. In the photo to the right, if you look carefully, there are two speckled eggs seen under the bird; also notice how plain the nest is. After the eggs are laid, Killdeer will add rocks, bits of shell, sticks and trash to the nest for camouflage.

Killdeer distract predators by running away, calling loudly and bobbing up and down. They are one of the best practitioners of the "broken-wing display," an attempt to lure predators away from the nest by feigning injury. After the predator follows the adult  bird away from the nest, the adult then flies off. This broken-wing display does not prevent cows or horses from stepping on eggs. In cases like these, the Killdeer fluffs itself up, displaying its tail over its head and charging the beast in an attempt to get it to change its path.

Killdeer's "broken-wing act"
Typical brood is four to six eggs which are incubated for 22 to 28 days. Chicks can walk as soon as their feathers dry.

Killdeer get their name from the shrill, wailing kill-deer call. Eighteen-century naturalists used to call them "Chattering Plovers" or "Noisy Plovers."

Plant your garden with birds in mind

You can do a lot for birds in your own backyard, beyond putting out seed and a bird bath. By diversifying the plants in your backyard and providing resting and nesting places as well as food during all seasons, you can attract many species of birds.

There is a symbiotic relationship between birds and plants that is revealed in the wild and in the garden. Plants depend on birds to pollinate their flowers and have large blooms to attract them.


Serviceberry trees provide lots of fruit for birds
Plants that depend on birds to disperse their seeds have brightly colored fruit as seed-eating birds have a good eye for color. Most trees and shrubs bear small fruits, no more than three-fifths of an inch in diameter, which make it easier for birds to eat.

Now is a good time to plant trees, shrubs and perennials in your backyard. Nurseries are eager to sell off their plants so they won't have to carry their inventory over the winter. You'll see large discounts on plants. The plants may not look as good as they do in their summertime glory but that's to be expected. They're winding down for the colder months. But be sure to get your new plants in the ground right away. That way they'll have time to extend their roots before the ground freezes so they'll flourish in the spring.

Here are some guidelines in establishing a bird garden:


  • Re-create layers of plant growth found in woodlands--canopy, understory, shrubs and ground layer.
  • Select plants so that there is food in all seasons.
  • Plant small trees and shrubs in same-species clumps to boost cross-pollination and fruit growth.
  • Plant some evergreens which birds use for cover during storms.
  • Plant vines for fruit or perching.
  • Leave a dead tree for birds to perch on, to use as a singing post, or for woodpeckers to carve out nesting cavities.
  • Supply a source of water for drinking, bathing or cooling off.
  • Provide nesting boxes, which are good substitutes for increasingly scarce natural tree cavities.
  • Leave lots of leaf litter under trees and shrubs for robins, towhees and juncos that pick through the mulch for worms, insects and spiders.


Don't use pesticides which can harm birds directly or contaminate insects that birds eat. (A lawn company was none too pleased when I told them that pesticides did not fit into our natural habitat philosophy.)

Lady bugs devour aphids on perennial plants
Beneficial insects devour or destroy many garden pests. In the latter case,  insects called parasitoids develop an egg or larvae inside a host, ultimately killing it.

Studies suggest that native "composites," members of the wide-ranging aster family, have the best blossoms for attracting beneficial insects. Composites with daisy-like blossoms consist of tiny flowers packed together on a central disk surrounded by colorful ray flowers. Examples of these flowers are aster, coneflower and tickseed (coreopsis).

Many of these plants are directly beneficial to birds due to the seeds that develop in the coneflowers and coreopsis.


Goldfinches love coneflower seeds
And don't forget reddish-colored perennial plants such as bee balm, cardinal flower, red-hot poker plant and trumpet vine. Their flowers contain nectar which attracts hummingbirds.

Planting bird-friendly trees, shrubs and perennials now will make your backyard more inviting for birds when warm weather returns next year.
