This year my Nevin's Barberry (Berberis nevinii) truly made that leap and ‘came into its own’! Lovely, fragrant yellow flowers smothered the plant in early spring, right about the same time as many Ceanothus start to bloom; and then abundant, small red berries followed, maturing in June.
Gardening for the Birds
At the risk of sounding redundant, the first and most important thing to remember when planting “for the birds” is to include a lot of plants that attract and sustain insect populations. It’s also critical to preserve and protect the native plants already present, especially mature trees. Unless it’s a truly invasive nonnative species (such as a mature privet), any healthy tree will be a benefit to bird life because trees provide cover and nesting sites, and often some form of food as well. Avoid any major pruning work on trees and large shrubs during the nesting season; always schedule this kind of work between September and January or February.
Birds are really tuned in to the seasonal changes; average temperatures and day lengths trigger migrations to and from breeding areas and also amazing physical changes within a bird’s body. Their reproductive organs and digestive systems change to accommodate the needs of the next generation.
Diets change, seed eating birds may eat more fruits and greens, and when actually rearing nestlings, eighty percent of all songbirds rely on insects for the protein necessary for their fast growing offspring.
So, the basics of habitat gardening apply here as well: be sure your garden is a pesticide-free zone maintained using all organic, sustainable methods. Grow a variety of intermingled plant types to provide cover and shelter and food resources in each season, and provide a source of clean water. Letting your plan go to seed, mulching under plantings and leaving leaf litter are all practices that are beneficial for the birds.
Creating undisturbed brush piles, if it is allowed in your area, is beneficial to ground-nesting birds, and hanging nesting boxes will benefit cavity nesters. Growing various grasses and leaving the chaff after seed set provides nesting materials. Any nests from the previous seasons should be left in place as some birds will reuse old nests or scavenge materials from them.
Birds often return to their natal territories and there’s nothing quite as satisfying to a habitat gardener as knowing that certain wonderful birds will likely return to raise another generation in your resource-rich garden sanctuary!
All through the rainy season many birds rely on fruits as a major part of their diet. These birds often travel in flocks, like the Cedar Waxwings and American Robins. Sometimes the flocks are mixed; several different species will travel together, and all are “on the lookout” for resources.
Bright red berries are easy for birds to spot; and large quantities of fruits in one place make foraging more energy efficient. Red Toyon berries (Heteromeles arbutifolia) certainly attract the attention of hungry birds, but so do other red berries such as Cotoneaster and Pyracantha.
Whenever I'm out collecting I always keep it foremost in my mind that seeds are food for all sorts of insects and other invertebrates, for birds, rodents and other mammals, and food for humans!
When I gather toyon berries in December, I take just a handful from each cluster, and go to several different shrubs to collect. I want to make sure there’s still plenty of food for the birds; the red berries are a magnet for cedar waxwings, robins, house finches, band-tailed pigeons and the mockingbirds. By February, there are no more berries on the toyon.
