When In Drought…
When it comes to droughts, the costs of climate change are too high for both birds and people.

Patagioenas fasciata
Conservation status | Numbers were once seriously depleted by overhunting. With protection, made a fair comeback; in recent decades declining again, undoubtedly for different reasons. |
---|---|
Family | Pigeons and Doves |
Habitat | Oak canyons, foothills, chaparral, mountain forests. Mainly in wooded or semi-open habitats; moves around to take advantage of changing food supplies. Breeds in oak woodland along the coast and in mountains, also in pine-oak woods and fir forest. May forage along streams in lowland desert. Increasingly regular in suburban areas on Pacific Coast. |
Will forage on ground or in trees. Can climb about with great agility in small branches, even hanging upside down to reach berries. Usually forages in flocks, even during breeding season.
1, sometimes 2. White. Incubation is by both parents, 18-20 days. Young: Both parents feed young "pigeon milk." Young leave nest about 25-30 days after hatching, are tended by parents for some time thereafter. 2 broods per year, sometimes 3.

Mostly nuts, seeds, berries. Diet shifts with season. Acorns are major part of diet when available. Eats many berries, including those of elderberry, manzanita, juniper, wild grape, many others. Also eats seeds, tender young spruce cones, buds, young leaves, flowers, occasionally insects.
Several pairs may nest close together in loose colony. In courtship, male flies up and then glides in a wide circle, giving a wheezing call and fluttering wings toward end of glide. On perch, male coos with chest and neck puffed up, tail lowered and spread. Nest site is in coniferous or deciduous tree, usually 15-40' above ground, can be lower or much higher. Placed on fork of horizontal branch or at base of branch against trunk. Nest is a bulky but loosely-built platform of sticks; male brings material, female builds.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

These tiny scourges can cause mass casualties among avians.
