Flocks of Band-tailed Pigeons range from a single bird to fifty or more.
They perch in the tops of tall trees and are known to preen one another
for parasites such as lice, fleas, and ticks. The Band-tailed Pigeon typically
moves 32 - 40 km (20 - 26 mi) per day and are capable of flying through
rainstorms and high winds.
While feeding in grain fields, Band-tailed Pigeons in flock move as waves
of small groups, leapfrogging ahead. Occasionally, similar leapfrogging
downhill as birds feed on arboreal foods.
Will defend nest against predator by hissing and striking toward it with
the wrists of opened wings. Wing-slaps common by female when being courted
by male at feeding site.
Upon taking flight, at times, wings "clap" as they meet over
the back (and perhaps below the body, but softer), similar to Rock Dove.
Adults, especially in summer and particularly in the Pacific Coast region,
frequently visit natural springs and water bodies high in mineral salts,
where they rapidly peck at the soil or drink water intermittently, with
long bouts of roosting in nearby trees.
Drinks by inserting bill into water; appears to suck up a continuous
draught of liquid. Especially in n. Pacific Coast region, drinks water
and may ingest minerals encrusted on pebbles and soil at natural and artificially
created mineral deposits ("mineral springs"). Will peck at salt
licks on grazing range.
Food apparently found by small flocks of Band-tailed Pigeons, with tail
fanning when landing as a signal to others as to food location.
An Oregon study found that the average distance a Band-tailed Pigeon
traveled from its nest to a feeding site was 5 km (3.1 mi).
In trees, may hang upside down to pick off acorns, fruit, or buds. Swallows
acorns whole, without cap. Crop walls sometimes pierced by acorns; will
feed on pine cones fallen onto the ground. If undisturbed, appears to
feed to satiation.
Though the species has two distinct breeding populations in the United
States, individuals do move from one region to the other. One Band-tailed
Pigeon banded in Oregon was shot a year later in Florida, well outside
the normal range.
Female incubates at night, beginning late afternoon; male midday. Before
relieving incubating mate, incoming adult approaches nest from underneath,
hopping upward; after a quick changeover, off-duty adult flies away quickly,
but may roost nearby; incoming parent settles down smoothly. Eggs are
turned frequently, averaging 3 times a day, more frequent late in incubation.
Parent attentive, leaves nest rarely and briefly.
Pigeons produce food for their young that is unique from other types
of birds. "Pigeon's Milk" is a milky substance produced in the
birds crop (food-storage pouch which is the first stage in the birds digestive
tract). During the first few weeks of the nestling's life, the parents'
crops produce a thick, milky substance made of protein and fat. Gradually,
the parents add solid foods, softened by the milk, until their young are
ready for solids.
Rapid population declines in recent years have resulted in Band-tailed
Pigeons being listed as an Audubon
WatchList species.
