Tree Trimming During Nesting Season May Put Valley Birds at Risk

Summer tree trimming is underway across the Coachella Valley, but wildlife experts warn the annual maintenance could be putting protected bird species at risk.

At the Desert Wildlife Center in Indio, Director Mikah Curtis says the center is seeing an influx of baby birds, many of them injured or orphaned after nesting areas are disturbed.

Curtis says tree trimming often overlaps with bird nesting season, which in the Coachella Valley runs from February through the end of August.

During that time, hundreds of bird species build nests, lay eggs, and raise their young.

“If mom and dad are nearby and caring for them, the best thing to do is leave them where they are,” Curtis explained, adding that not every baby bird found on the ground needs human intervention.

But Curtis says one of the biggest threats to nesting birds is trimming trees while nests are active.

“We recommend holding off on trimming until September or October,” he said. “Any time between spring and summer, we really want to prevent tree trimming as much as possible so these birds have the best chance of staying in the wild with their parents.”

Wildlife experts say disturbing active nests can also have legal consequences. More than 98 percent of bird species in the United States are protected under the Migratory Bird Treaty Act, making it illegal to disturb nests containing eggs or baby birds.

In Indian Wells, homeowners are required to trim palm trees in June and July under a city ordinance dating back to 1993. Officials say the rule was created to address palm tree debris and fire concerns. Residents who fail to comply can face fines starting at $100 and increasing to $500.

After learning about the conflict between trimming schedules and nesting season, Indian Wells city leaders say they are open to reviewing the ordinance.

City Manager Christopher Freeland says the issue could also be brought before the Coachella Valley Association of Governments, which includes all nine valley cities and four tribal nations.

Curtis hopes more local governments, HOAs, and residents will consider adjusting tree trimming schedules to better protect nesting birds and preserve local wildlife.
