How can I trim trees safely and avoid impacts to birds?
After recognizing the significant threat to nesting birds posed by spring and summer tree trimming, the Los Angeles Audubon Society put out a nifty guide to bird-friendly tree trimming. The guide targets the Los Angeles County area, but most of the information applies to San Diego as well.
Overall, it is best to trim trees from fall to late winter, before birds begin to nest.
