California Nature: Cardinals & Grosbeak
|
|
The Cardinals are a family of passerine
birds that are robust, seed-eating birds, with strong bills.
They are typically associated with open woodland. The sexes
usually have distinct plumages. There are 43 species world wide,
13 North American species, and 10 Californian species.
The Northern Cardinal or Redbird or Common Cardinal (Cardinalis cardinalis) is a North American bird in the genus Cardinalis. It can be found in southern Canada, through the eastern United States from Maine to Texas and south through Mexico. It can also be found on the Big Island of Hawaii and on Oahu. It is found in woodlands, gardens, shrublands, and swamps.
The Black-headed Grosbeak prefers to live in deciduous and mixed
wooded areas. It likes to be in areas where there are large
trees as well as thick bushes, such as patches of broadleaved
trees and shrubs within conifer forests, including streamside
corridors, river bottoms, lakeshores, wetlands, and suburban
areas. It also seems to avoid coniferous vegetation.

The Black-headed Grosbeak is a small migratory
bird which lives in a wide range, spanning from
southwestern British Columbia to the western
half of the United States, to central Mexico and
rarely Central America. During the winter
months, this species typically flies to Mexico
to dine on the poisonous Monarch butterfly and
berries. This species has an affinity for
deciduous and mixed woodlands, favoring areas
with large trees and numerous shrubs. They also
tend to avoid coniferous woodlands. Their normal
diet consists of pine tree and other seeds,
berries, spiders, insects and fruit.
Black-headed Grosbeak are a large, stocky finch
with black-streaked, orange-brown back, and black head, wings,
and tail. Their breast is orange-brown and belly is yellow. Wings have conspicuous white patches,
these birds have black legs and feet. Foraging on
the ground and in trees and bushes, the
black-headed grosbeak eats insects, caterpillars, seeds, fruits and berries.
Black-headed grosbeak nests are so thinly constructed that eggs
can be seen through the bottom. However, nests
are less thin in northern California. Thin nests
may provide ventilation and help keep them cool.

The male Northern Cardinal is perhaps
responsible for getting more people to open up a field guide
than any other bird. They’re a perfect combination of
familiarity, conspicuousness, and style: a shade of red you
can’t take your eyes off. Even the brown females sport a sharp
crest and warm red accents. Cardinals don’t migrate and they
don’t molt into a dull plumage, so they’re still breathtaking in
winter’s snowy backyards. In summer, their sweet whistles are
one of the first sounds of the morning.
Only a few female North American songbirds sing, but the female
Northern Cardinal does, and often while sitting on the nest.
This may give the male information about when to bring food to
the nest. A mated pair shares song phrases, but the female may
sing a longer and slightly more complex song than the male.
A perennial favorite among people, the Northern Cardinal is the
state bird of seven states.

Many people are perplexed each spring by the sight of a cardinal
attacking its reflection in a window, car mirror, or shiny
bumper. Both males and females do this, and most often in spring
and early summer when they are obsessed with defending their
territory against any intruders. Birds may spend hours fighting
these intruders without giving up. A few weeks later, as levels
of aggressive hormones subside, these attacks should end.
Look for Northern Cardinals in dense shrubby
areas such as forest edges, overgrown fields, hedgerows,
backyards, marshy thickets, mesquite, re-growing forest, and
ornamental landscaping. Cardinals nest in dense foliage and look
for conspicuous, fairly high perches for singing. Growth of
towns and suburbs across eastern North America has helped the
cardinal expand its range northward.
Northern Cardinals eat mainly seeds and fruit, supplementing
these with insects (and feeding nestlings mostly insects).
Common fruits and seeds include dogwood, wild grape, buckwheat,
grasses, sedges, mulberry, hackberry, blackberry, sumac,
tulip-tree, and corn. Cardinals eat many kinds of birdseed,
particularly black oil sunflower seed. They also eat beetles,
crickets, katydids, leafhoppers, cicadas, flies, centipedes,
spiders, butterflies, and moths. |

The cardinal is about eight inches in
length. It has a black mask on its face, a crest on its head and
a short cone-shaped bill. The mask on the female is usually
lighter than the mask on the male. Cardinals are known for their
bright red color but only the male is red. The females is a dull
brown or olive color with dull red on her wings and tail.
Cardinals usually raise two broods of young a
year. They mate in March and again from May to July. The female
usually lays four eggs. The eggs take about 12 days to hatch.
Cardinals usually build cup-shaped nests in small trees, bushes,
shrubs and thick vines that are no more than three to eight feet
off the ground. Their nests are made of twigs and bark and are
lined with grass, moss and other soft materials. Young cardinals
leave the nest after 11 days and they can fly within 20 days.
