Can Humming Birds Sit Down?

I've heard them all! Hummingbirds can't sit down because ... they can't sit still; they have to eat constantly; and my favorite, they don't have feet. All of these, however, are false. Hummingbirds can sit down.



 

Do hummingbirds sing?

Hummingbirds make chirps and peeps that have been
described as 'creaky hinges' and 'squeaky wheels'. Listen

Now I ask you, if a hummingbird couldn't sit down, how would they lay an egg? It would be quite a feat of skill, aiming an egg coming from their posterior into such a tiny nest on the fly. I'd be even more impressed with these little birds than I already am.

Hummingbirds have very high metabolisms thus requiring them to search for food during most of their waking hours. During this daily activity they take short breaks to sit on tiny branches and preen. Often hummingbirds will sing from these perches as well. To me, their song sounds remarkably like a squeaky wagon wheel.

When it comes to being still, sleeping does pose a challenge. A hummingbird's high metabolism may cause them to starve over the short duration of a single night. To avoid this, hummingbirds go into a torpor when asleep. Similar to dormancy, torpor is a deep sleep during which the animal's metabolism slows down, thus requiring less energy. The difference between this and dormancy is that, when in torpor, a hummingbird can be roused by outside stimuli whereas an animal that is dormant cannot.

If Hummingbirds Can't Sit Still for Long, How Do They Sit on Their Eggs?



By Kevin Bondelli


Hummingbirds spend very little time sitting on their eggs. The mother hummingbird used quite of bit of her body's resources to produce two eggs and therefore, she needs to build up her energy by eating even more than she typically would. And, she will soon have two more mouths to feed.
 
Female hummingbirds are single parents and therefore, planning ahead is a must! Because she will spend little time sitting on her eggs, she needs day care. This comes in the form of a cleverly designed nest that holds the eggs securely until they hatch and then stretches with the hatchlings as they grow. Cleverly, she builds her nest out of spider webs. The nest keeps the eggs snug, safe and provides insulation. After hatching, the nest flexes and grows along with the chicks.

Bug or Bird?

There is a large family of moths, the hawk moths (Sphingidae), that can easily be mistaken for hummingbirds. While these moths are slightly smaller than hummingbirds, they also hover and fly forwards or backwards. As hawk moths hover in front of flowers they sip nectar with their long proboscises and are important pollinators.

Have you ever wondered how a hummingbird drinks nectar? Even though their beaks are long and narrow, they don't work like straws. Without lips or cheeks they can't create suction to draw up the nectar. So how do they do it? They use their long, thin tongues. Really! Their long beaks reach into the flower and then they stick their tongues into the nectar to draw it into their mouths. Check out the hummingbird's tongue sticking out of its beak in the photo to the right.

Often, if you see something that you think is a hummingbird flying about your flowers at dusk, it is likely to be a hawk moth. Like hummingbirds, the hawk moths' wing beat so quickly that they make a buzzing sound. Unlike hummingbirds, hawk moths have antennae - a dead give away that they are insects and not birds!

A flash, a buzz, here, now gone.

  1. This is exactly the information I was looking for! We have a nest in the crook of a large, plant-like tree on our balcony, and I've seen the mother come and go. She's very chirpy, so it's easy to tell when she's around. She seems to be attracted by my music (horn and piano), because her chirps accompany my playing. However, she doesn't seem to spend much time sitting on the egg. I was worried that perhaps the "chicklet" in the egg was dead or would die. I'm so relieved to learn that this behavior is to be expected.

  3. I have a couple of hummingbirds that visit my feeder, it's the first year I've had one, and one of them always sits on top of the shepards hook I have it hanging on like it's just chillin

  4. I have an Anna female I believe, for the past week and a half she comes at dawn to the feeder and leaves at dusk. She "sits" there all day. She is not a bully to the other hummers, female and males come to drink. No matter what the weather she just sits there. I see her drink occasionally. I can walk up to her about a foot or even less away from the feeder. She just looks at me. I tell her I need to change out the feeder ( this is about every 3 days) she flies off to the nearest branch waits for me to make the exchange and flies back. I worry as I never see her fluttering about as the other birds do. This is going on the 3rd feeder exchange so 9 days that I have noticed her. She appears to be ok. Tongue in mouth. Fluffy. But rain, wind or sun she just sits there. I worry about her water intake too.
    I can't find anything on a hummer that does this.
