Hummingbirds are one of the most aggressive, selfish birds we have in north Texas. They’re bullies. Thank heavens they’re so small or they might try to take over the world… or at least every tree and birdfeeder in it. They'll chase others from feeders, even if the "chaser" isn't hungry. Juvenile hummingbirds, especially, seem to frequent feeders where they don’t get chased away.
Ladybug, don’t fly away home
If you control insects with Ladybugs (and lots of people do) we recommend that you release them at dusk. Why? Since you have the domestic variety (and you should!), they instinctively return to their birthplace – probably in the Rocky Mt. foothills. But they don’t fly at night. So, by releasing them at dusk they’ll stay in your yard and lay lots of eggs. And hungry birds won’t get them at night.
Asian Ladybugs were imported and let loose several years ago. They can get in your house and become a nuisance. Don’t buy them!
