This was mentioned in today's Daybreak Community Update:

QUOTE:
You may have noticed swallows that have nested under the bridges on11400 S. The Association has looked into these particular birds and they are federally protected species of bird and we are not able to tamper with the nests until after they migrate this fall. Once the birds have migrated we will go through the area and clean up their nests.

It's VERY important that we do EVERYTHING we can to keep the swallows here at Daybreak!

Every day, a cliff swallow eats 3 POUNDS of mosquitoes (and other flying insects). The swallows are the BEST way to keep the mosquito population under control and we should do everything we can to encourage them to stay here and make Daybreak their home.

Here is a Wikipedia article about them:

Here is the article giving the estimate of insects that a swallow can eat each day:

Don’t be a Hoser or The Swallows of California

If any of you have any power with the HOA, please get the word out about how helpful these birds can be.
