Barred Owls Are October Birds on the 2022 Audubon Calendar

Summary: Barred owls are October birds on the 2022 Audubon calendar whereby the National Audubon Society alerts Unitedstatesians to North American vulnerable birds.

John James Audubon (April 26, 1785-Jan. 27, 1851) artistically addresses predator-prey activities on plate 46 in his Birds of America, available between 1827 and 1838. He assembles one predatory barred owl with one gray squirrel prey. Amphibians, birds, crabs, crayfishes, insects, reptiles, small mammals and spiders are among what barred owls appreciate as prey; John James Audubon, The Birds of America From Original Drawings (1827-1830), No. 10 Plate XLVI: Public Domain, via Wikimedia Commons

Barred owls are October birds on the 2022 Audubon calendar whereby the National Audubon Society alerts, by associating each month with a different avian, Unitedstatesians to 12 vulnerable birds in North America.

Wintertime, springtime, summertime bird and squirrel backyard feeders bring Strigiformes (from Greek στρίξ [“screecher”] via Latin strix and Latin -fōrmēs [“-shaped”]) nocturnal, solitary raptor order members. That order contains Strigidae true, typical owl and Tytonidae (from Greek τυτώ via Latin tutubō [“to cry”] and Greek -ειδής [“-like”] via Latin -idæ) barn-owl families. Barred owls dwell as Strigidae family members in deep woodlands and mixed hardwoods midcontinent through eastern and southern coastlines, northwesternmost conifer rainforests and southern cypress swamps.

Physically and sexually mature females, minimally two years old, engender, each year in 18-year-lifespans, one one- to five-egg clutch during breeding-season months from January through September.

Barred owls fit a second brood into one-brood seasons if first-brood eggs fail to hatch or if first-clutch hatchlings fail as nestlings, fledglings or four-plus month-olds.

Mature females gestate in 15- to 30-foot- (4.57- to 9.14-meter-) high abandoned hawk, squirrel or stick nests or natural unlined cavities in conifer-forest stubs and trunks. They have no spousal help hatching elliptical to near-spherical to semi-elliptical, semi-glossy, smooth, white 49- by 42-millimeter (1.93- by 1.65-inch) eggs within 28 to 33 days. Altricial (helpless, from Latin altrix, “[female] nourisher”) hatchlings impart light-colored, thick softness with first coats of white down and with second coats of buffy, white down.

Barred owls journey through the 2022 Audubon calendar as October birds, during which month barred owl fathers, previously uninvolved, join their mates feeding and tending nestlings.

Barred owl hatchlings keep eyes closed their first seven days and know their first three weeks as nestlings kept in birth nests under 24/7 co-parental care.

Nestlings as four- to five-week-olds sometimes leave for branches located close to birth nests even as they lack gliding, wing-flapping flying skills until their sixth week. Barred owls maintain solitary lifestyles outside mating seasons even as their fledglings meet them for father- and mother-managed meals through four to five months after birth. Insects, spiders and small amphibians, birds, crabs, crayfishes, mammals and reptiles nourish female and male, juvenile and mature barred owls (Strix varia [“screech diverse” literally] scientifically).

The 2022 Audubon calendar offers as October birds nocturnal barred owls, nevertheless obvious day and night in observing choral and solo calls and organizing hunting operations.

Physically and sexually mature barred owls possess 17- to 19.5-inch (43- to 50-centimeter) body lengths, 3.5-foot (1.1-meter) wingspans and 17- to 37-ounce (475- to 1,050-ounce) weights.

Brown and white qualify as barred owl colors, with brown eyes and upperparts, brown- and white-barred breasts and tails and brown- and white-streaked bellies and heads. Barred owls release through their yellow beaks choral and solo barks, cackles, caws, guttural sounds, screams and signature hoo hoo hoo-hoo, hoo hoo, hoo hoo-aw hoots. The latter call, rhythmically submitted from daytime, night-time perches, sounds like “Who cooks for you? Who cooks for you all?” to master gardeners and master naturalists.

The 2022 Audubon calendar treats as October birds barred owls, treasured in three countries ever since Benjamin Smith Barton (Feb. 10, 1766-Dec. 19, 1815) taxonomized them.
