Search of the Week: “it is september why am i only getting female hummingbirds at my feeders…”

In juvenile plumage, young male hummingbirds like this Ruby-throated usually look a lot like their mothers. They also seem to leave the nest with chips on their shoulders.

In juvenile plumage, young male hummingbirds like this Ruby-throated usually look a lot like their mothers. They also seem to leave the nest with chips on their shoulders.

The full search was: “it is september why am i only getting female hummingbirds at my feeders and she is very aggressive”

By September, most of the migratory hummingbirds remaining at northern latitudes will be young birds of both sexes, which look like adult females except for variable amounts of pale fringing on the iridescent feathers of their backs and heads (plus a few other subtle differences, depending on species). Young males often show lines of dark spots on the throat, a pattern hummingbirders call “five-o’clock shadow.” Some young males will show bright flashes of color in their gorgets as adult feathers replace drab juvenile ones.

Though females of any age can be very aggressive and territorial, especially in migration, it’s the young males that seem to be the biggest troublemakers (as though they think they have something to prove). As long as there are still good numbers of hummingbirds around, expect the screeching, chasing, grappling, and chest-bumping to continue.

Keeping hummingbird feeders clean

Hummingbird Feeder Cleaning Kit

If you’re like me, you’ve got a collection of toothbrushes, baby bottle brushes, and even well-washed mascara brushes sitting next to your kitchen sink for cleaning hummingbird feeders. The problem is that tools made for other cleaning jobs don’t always work as well for such a specialized task, so it’s nice to see a set of brushes made especially to reach the nooks and crannies of typical hummingbird feeders. The big brush in this set could even get into the enclosed bases of some of the cheapo feeder models to remove crud you can’t see.

Of all the nasties that grow on hummingbird feeders, the nastiest and hardest to control is black mold. A 15-minute soak in a dilute solution of chlorine bleach*⇓ (1 part bleach in 10 or more parts water) is very effective at killing black mold on non-porous surfaces, but an hour-long soak in white vinegar is a less toxic alternative (NEVER use bleach and vinegar together: you could kill yourself!). In either case, follow up the soak with a thorough brushing to remove dead mold colonies and other organic growths, then rinse well and let the feeder dry before refilling to allow the odor to dissipate.

An even safer mold killer that’s much kinder to your nose than bleach or vinegar is 3% hydrogen peroxide, the medicinal kind you can buy in any drug or grocery store. The downside is that it’s much more expensive than bleach or vinegar. A frugal alternative to traditional soaking is to add a couple of ounces to the feeder bottle, screw on the base, invert the feeder and swirl gently over a sink or bucket to make sure the peroxide covers all inside surfaces, then allow it to stand for at least 10 minutes. While the peroxide is doing its work from the inside, spray the outside with more peroxide to kill any mold growing there. Follow the treatment with a good scrub, including the ports. and rinse well to remove any debris. No drying needed; the peroxide will leave no odor, and the only residues are water and oxygen.

This advice applies mainly to bottle-style feeders. Saucer feeders such as the Aspects Hummzingers can be cleaned by hand using dish detergent and the small port brush in the kit above or washed on the top rack of the dishwasher. If any stubborn debris accumulates in the built-in ant moat, the little ball-shaped brush in the Brushtech set will swish it away.

Regardless of what type of feeder you have, it will need cleaning and refilling every 1 to 3 days in hot, windy, and/or rainy weather and every 4 to 6 days in cooler, calmer, drier weather, whether the birds have emptied it or not. If you can’t make a commitment to good feeder hygiene, it’s best to plant flowers instead.


* There’s a persistent myth that using chlorine bleach to clean feeders will kill hummingbirds. It won’t as long as you rinse the feeder well, just as you would if using bleach to disinfect your own dishes or your pets’ dishes. Any minute traces of chlorine residue will be rendered harmless by reacting with the sugar in the feeder solution (the same thing happens when you mix sugar with chlorinated tap water).

What Not To Wear Cranewatching

The Sandhill Cranes that winter at Whitewater Draw Wildlife Area have learned that humans are mostly harmless within the no-hunting zone.

The Sandhill Cranes that winter at Whitewater Draw Wildlife Area have grown accustomed to crowds of humans ogling them from the trails and viewing platforms.

Sandhill Cranes have returned to southeastern Arizona for the winter, and I’ll be visiting the flock at Whitewater Draw Wildlife Area almost every weekend between now and the end of February. When you have the privilege of spending a lot of time with cranes, you get to see lots of interesting behavior and interactions. Some are hard to miss, but the subtle ones can be the most educational.

One Sunday last February, I was leading a crane watch activity for the public on one of the viewing platforms at the wildlife area. Uncommonly cold temperatures that day kept most visitors away, but a handful of hardy souls joined me to watch the midday crane fly-in. The viewing platform has no roof or walls to block the wind, but spectacular unobstructed views of thousands of cranes made the eye-watering cold worth braving.

Drought had shrunk the playa lake to its lowest level in many years, and the scarcity of open water encouraged the cranes to land even closer to the viewing area than usual. They dropped in a few dozen yards in front of the platform, often skating across patches of ice (and sometimes falling down). The nearest birds cautiously picked their way across the frozen mud to a narrow band of open water a few yards from the platform and bent their long, graceful necks to drink. Camera shutters clicked madly, recording the spectacle.

The idyllic mood was broken by a sudden commotion east of the platform: a group of cranes scuttling warily away from a popular viewing spot on the trail, their necks extended and red crowns expanded in alarm. Peering through the leafless willows to see what had frightened the cranes, we saw four men dressed in varying degrees of hunting camouflage. All wore shirts and billed caps in camo patterns, and at least one wore coordinating pants. They weren’t accompanied by a dog (whose mere presence, even leashed, is known to have negative effects on birds and other wildlife), and none were carrying rifles or shotguns.

A dozen or so people in street clothes of various colors and at least three leashed dogs had already walked past that same spot without discouraging the cranes from approaching the trail. Maybe one of the men pantomimed shooting at the cranes, but it seems more likely that the older, more experienced members of the flock had learned to associate camo-clad humans with danger and reacted to the clothing alone.

Though I’m a strong proponent of dressing inconspicuously for birding, this experience has caused me to have second thoughts about whether hunting-style camo is a good choice for field wear, at least for watching cranes and other hunted birds.

Beware the wrath of the birding legions!

On Monday morning, the New York Daily News broke a story about the Port Authority killing Snowy Owls at airports in New York City. Follow-up articles contrasted trigger-happy NYC with the more responsible and humane policies of Boston’s Logan Airport (a famous location for wintering Snowy Owls). The story quickly spread via Facebook, prompting a petition and phone campaign to stop the carnage (three owls had already been shotgunned by the PA’s euphemistically named “wildlife specialists” after five others struck planes).

Usually such efforts take days, weeks, or months to bear fruit, and some never do, but by Monday evening the PA had come around and agreed to stop slaughtering the owls and cooperate with trapping and relocation. The outrage from the public, including the birding community, was so swift and so fierce that it overcame bureaucratic inertia.

Every day on social media we see calls to action in support of one good cause or another or against the latest outrage. It’s good to know that raising our voices and signing our names can make a difference.

Montezuma Quail are the topic for my final “Dispatches from the West” column in the September/October issue of WildBird magazine. Here’s a teaser:

Our hearts pounded as we drank in every detail of his harlequin plumage. The quail stared back, and we could almost hear the gears slowly turning in his head. It finally seemed to dawn on him that he’d been spotted, and he slowly turned and strolled away, watching us over his shoulder.

This is usually where I encourage you to subscribe if you don’t already, but it’s too late. After being informed that WildBird was downsizing and no longer able to publish my column, I was saddened (but not surprised) to learn that the magazine will soon cease publication entirely.

WildBird‘s parent company, Bowtie Incorporated, publishes annual special issues on popular topics, and I hope to contribute to any issues covering wild birds. I’ll also be releasing my past columns and articles, along with other selected writings, in e-book form later this year. Thanks and best wishes to the staff of WildBird for so many years of reading enjoyment, and thanks to the subscribers and newsstand readers for supporting the magazine.

Dispatches from the West Preview: March/April 2012

My column in WildBird magazine changed focus recently from backyard birding to western birding. Here’s a teaser from the March/April column, entitled “Bird prepared,” about a spring visit to Big Bend National Park:

The birds had gone quiet, so now we paused only to catch our breath. Neither of us noticed the waning light until a few raindrops hit our bare arms. Overhead, tendrils of mist trailed over the jagged South Rim. Just an isolated desert shower, we thought. Nothing to worry about, surely, and the cool air feels nice.
