Colorful fruit and berries that ripen in autumn and winter bring more than their own color to the garden. They also attract all sorts of birds. Some birds want to fatten up on the earlier and typically more abundant and colorful fruit before migrating south for the winter. Other birds that stay through winter eat fruit and berries that develop over a longer season, after the migratory birds are gone.
The most abundant and brightly colored red fruit of pyracantha (or firethorn) appeals to the early migratory birds that want to fatten up fast and get south. Cotoneaster, toyon and English hawthorn are not quite as flashy, but appeal to the same crowd of migratory birds. These sorts of plants get their colorful fruit early on in the season, but are then stripped of it rather efficiently.
The fruit of pyracantha, cotoneaster and toyon is not often very messy since almost all of it gets consumed; but the birds that eat it can be remarkably messy before they fly south. Coincidentally, these three plants are often grown as informal hedges and screens around the perimeters of large parking lots, so the mess is a traditional nuisance for many parked cars this time of year.
Chokeberry and elderberry ripen early enough for the migratory birds, but do not get devoured so efficiently because they are not so brightly colored. Migratory birds seem to prefer bright red or orange berries, so are likely to leave black chokeberries and blue elderberries for overwintering birds, which stay through winter. Strawberry tree, although not very productive, appeals to both crowds, and anyone else who might be interested in their fruit, by producing bright red berries throughout the year.
Persimmon, holly, loquat, some mahonia and some crabapple are even a bit more selective, by ripening their fruit later in autumn and winter after the migratory birds are gone. Pomegranate fruit splits open in the middle of winter, exposing a buffet of juicy red berries with meaty seeds for anyone who hasn’t gone south for the winter. Many pittosporums do the same, but without the colorful advertisement. Of course, most of us want to get our persimmons, loquats and pomegranates before the birds do!
Citrus such as lemons, oranges, grapefruits and mandarins that ripen later in winter do not attract birds, so we only need to share these fruits with our friends and neighbors. Citrus are colorful enough on their own anyway.
