Ruby-throated Hummingbird


When you see him up-close he looks rather menacing.

But striking fear is no small feat for a bird that weighs the equivalent of a couple coins…two cents. He’s fast, alert and always on guard for his enemies. Darting, dodging and dipping through flowers, he carefully evaluates where to stick his beak  before choosing a blossom.


He prefers red flowers and all the flowers in his blossom claim belong solely to him. This Ruby-throated Hummingbird has a greedy streak when it comes to food.  He is not into sharing.  Other male hummingbirds are not welcome and are quickly turned upon.  Fights occur whenever another male intrudes upon his territory and the strongest wins…there will be no sharing. His aggressive nature is directed towards females, too, although females are gradually and grudgingly accepted.


The slightly larger female lacks the iridescent throat of the male, but she shares a similar blue-green iridescent backside.  His beautifully bejeweled  throat undoubtedly impresses her.   She chooses a male after an elaborate courting display, including acrobatic flying, sunlit throat displays and steep dives at her.

Nectar is not enough for a Ruby-throated Hummingbird to survive upon, so insects fulfill his protein requirements.  He can pluck a mosquito from the air or hover at a web to relieve a spider of her catch.  He would dine on the spider, too, if she were silly enough to stick around.


Small feats of intimidation serve the Ruby-throated Hummingbird well.  He is the most prolific hummingbird east of the Rocky Mountains. 

As for his actual real live feet, he can’t walk very well…tiny feet.  He prefers to fly everywhere.

Hummingbird Feeders


A bit of a controversy surrounds when to stop feeding hummingbirds coming to your backyard feeder each fall.

Some people say September 1st, while others claim it is all right to leave it hanging until the hummingbirds leave.  The argument suggests that the hummingbirds would be encouraged to stay around an artificial food source too long and might not migrate early enough to survive. 

I spotted several female Ruby-throated Hummingbirds in Lake Park, Milwaukee recently, looking healthy and capable of migrating whenever they felt like it. They were alternating between loading up on jewelweed nectar for one minute and resting on branches the next.  The scene was mostly peaceful with many fall flowers available, but a few nectar squabbles broke out anyway. 

The Cornell Lab of Ornithology claims the need to take down feeders early because it discourages a timely migration is a myth.  Hummingbirds, like other birds, are more likely to leave naturally because of the shortening hours of daylight, rather than the availability of food. 

They seem to know naturally when to leave for their own good and no amount of feeder food will encourage them to stick around when it is time to go.  Cornell Lab even recommends you leave your feeder up for a couple of weeks after seeing the last hummingbird to supplement any stragglers that may have timed their departure poorly.  

Taking it down or leaving it up, a feeder is largely for our enjoyment anyway.  There is a female Ruby-throated Hummingbird hovering six-inches outside my window right now.
