Why Are Birds Eating My Flowers?

Hummingbirds aren't the only nectar-eaters out there! Tanagers, orioles, grosbeaks, and finches also have a taste for the sugary fluid, but don’t have the anatomy to gracefully sip as they flutter from bloom to bloom.

Spring gives a promise of increased bird activity and fresh floral blossoms, but what does it mean when your feathered friends are preying on petals? If you maintain a garden in your yard, there's a reasonable chance that you've noticed birds plucking at your blooms at some point. While this behavior can sometimes be attributed to actual flower-eating, also called florivory, it's possible that those birds tearing at your blossoms are practicing something else entirely.

Incidental Foraging

It could be that a bird is simply sampling the smorgasbord of your backyard as it's plucking away in your garden. Hungry birds, especially juveniles, will peck at a variety of objects to figure out what items are edible and palatable, and where to find them. These avian browsers may nibble on a wide range of flowers of different colors, sizes, and shapes as they seek out effective sustenance.

Insectivory

If you're a gardener, you've no doubt observed that flowers house several species of insects and arachnids. Birds are also keen to this fact, and will rifle through your planters in search of bugs to eat. Unfortunately, some petals might be lost in the process.

Nectivory

Hummingbirds aren't the only nectar-eaters out there! Tanagers, orioles, grosbeaks, and finches also have a taste for the sugary fluid, but don't have the anatomy to gracefully sip as they flutter from bloom to bloom. Instead, these species have to bite flowers off of their stems to access nectar. The voracity with which they process the flowers in their bills may give an appearance of florivory, but they are actually consuming the plant's nectar.

Displacement Behavior

It has been observed that animals that don't compete well with others within their social group will make eye-catching inanimate objects the target of their unspent aggression. Socially frustrated birds tend to vent their disgruntlement on brightly colored things, and flowers are easy victims. A male mockingbird with low social status, having put up with rejection by females and harassment by higher-up males, might take its hard feelings out on a forsythia, destructively pulling off the yellow blossoms with no intention of eating them.

  • Love listeningto both songs and calls from birds in our woody neighborhood. The two types of birds I immediately recognize are the cardinals and the chickadees. Yesterday afternoon too, I heard a woodpecker. Then it’s time to check the birdfeeders and the birdbath. Then In no time at all the cardinals and chickadees arrive, as if they had been watching me. As it gets busier around the feeders, I also hear thé screeching of the blue jays. I even saw a couple of robins checking out our lawn....spring has arrived as the last pat gesofisticeerde snow and ice melt away.

  • I am wondering about existing nests for Phoebes. I have two outdoor aisle entries to my barn and there are old Phoebe nests up. They ignore them each year and build new nests adjacent to the old, but space is running out. Should I knock down the old nests so they can rebuild?

  • New to birding...newbie question. We spotted what we thought was a Sapsucker at our patio feeders in December. The folks at our birding supply store told us that Sapsuckers are only here in Summer months and what we saw was a Flicker. I thought I new what a Flicker was and this did not look like a Flicker. It was thinner and more smooth looking but did have the Woodpecker Bill.
