Hummingbirds are the only species that can say “small but powerful.” It frequently leads us to wonder about the size of these birds’ nests when we’re admiring their small size. And then there are those little eggs! And there are little ones in attendance! What do baby hummingbirds eat since we don’t spot them at our hummingbird feeders?
The female hummingbird is entirely on her own when it comes to building the nest and raising the young after she has been fertilized by the male. It will take a female about a week to make her tiny cup-shaped nest. Moss, lichen, plant fibers, pieces of bark, and leaves are used to construct the nests. Spiderweb silk is also used. Two eggs are usually produced, however only one is produced on rare occasions. Since they may assist to keep each other warm while their mother is away from the nest hunting food, two chicks are more likely to survive if they are born.
Hummingbird infants are quite tiny. They’re just about 2 centimeters long and weigh less than one gram each. Their eyes are closed and they don’t have feathers when they’re first born. Their eyes will not open for another two weeks, and their feathers will not emerge for another two weeks.
The length of time it takes for babies to leave the nest varies somewhat between species. Hummingbird youngsters leave the nest three weeks following hatching, on average.
HOW DO BABY HUMMINGBIRDS EAT
The crop, which is found in the throat of hummingbirds, is very unique. The esophagus is essentially a storage space for food, which is stored in the crop. This may be utilized by adults to collect excess food for future use. To be eaten and digested, food in the crop must be secreted down to the stomach. On days when food is scarce, this is a helpful feature. The crop of female hummingbirds may also be used to collect food for their young.
The juvenile hummingbirds’ eyes are closed for many days following their birth. The infants can sense if their mother is approaching in a variety of ways, including listening for chirps and feeling vibrations in the nest caused by her landing or wings. They’ll raise their heads out of the nest and open their mouths in anticipation of her when they sense her.
Mom will put her beak into the mouth of the babies and spew the contents of her crop down their throats when they open their mouths to beg for food. At the time of feeding, the food in the crop has not made its way to her stomach, therefore it is undigested.
WHAT DO BABY HUMMINGBIRDS EAT
The mother feeds small insects and nectar to her baby hummingbirds. Feedings will take place every 2-3 hours on average. Insects versus nectar provided to the young varies by species and habitat, with some insects feeding more than others. However, it is critical to offer as many insects as feasible. Nectar alone cannot provide the nutrients, proteins, and fats that a growing and developing child requires.
One of hummingbirds’ favorite insects to catch is small spiders. Mosquitoes, gnats, fruit flies, ants, aphids, and mites are all eaten by hummingbirds. Insects may be plucked off branches and leaves with their long bill and tongue. Insect catching mid-air is another talent they have, referred to as “hawking.”
The mother may continue to assist feed the juvenile for another 1-2 weeks after they have left the nest. In addition to teaching them how to hunt for their own meals, I taught them a couple of things.

WHAT TO DO WITH ABANDONED BABY HUMMINGBIRDS
Finding an abandoned baby bird is a fear for all nature lovers. Caring for a baby hummingbird is a complicated and sensitive process. Even the most well-meaning individuals may attempt and fail to rescue a bird that does not require rescuing. Let’s start by discussing how to tell if a nest has been abandoned safely before we do anything else. Following that, we’ll provide guidance on how to raise baby hummingbirds while obtaining professional aid from the San Diego Humane Society’s Project Wildlife.
HOW TO TELL IF A HUMMINGBIRD NEST HAS BEEN ABANDONED
The most frequent cause for concern is when a newborn is seen in a nest with no adults around. The mother must sit on the nest continuously to keep the chicks warm when they are freshly hatched and have no feathers. However, once the chicks have developed their own feathers (around 10-12 days following hatch), this drastically changes.
She no longer has to sit on the nest since the babies have learnt how to keep themselves warm. To avoid attracting the curiosity of possible predators, she will spend the most of her time (day and night) away from the nest. Mom returns to the nest for a brief visit to feed the babies before leaving. These mealtime visits may last just a few seconds. This happens on average every hour or so, but it may take as long as an hour or more between visits in certain situations.
Imagine how a worried nest observer might miss seeing these short feedings and think that the mother has abandoned the nest. Before you can say for sure if the adult is returning, you must watch a nest for two hours continuously.
Also, be aware of silent infants who are not. Quiet newborns who aren’t crying and aren’t chirping don’t mean they’re unwell, contrary to popular belief. Hummingbirds employ another method of protection against predators by remaining quiet; they don’t want to attract the wrong type. When Mom passes by to feed them, they’ll frequently cry and chirp, but as soon as she returns, they’re quiet again. Hummingbird babies who are left alone for ten or more minutes without seeing a parent might be indicating they are in trouble.
IF YOU FIND A HATCHLING HUMMINGBIRD
Hatchlings are born with gray/black skin and no indication of feathers, or just pin-feathers that are not fluffy and tube-like, and they are 0 to 9 days old.
- Don’t attempt to feed these infants; get assistance right away!
- Try to keep the baby in the nest as long as possible.
- Line a small container with tissue and place the baby near a heat producing lamp if a nest isn’t accessible.
- If the baby is open-mouth breathing or stretching his neck out, it’s too hot; reduce the heat.
IF YOU FIND A NESTLING HUMMINGBIRD
The nestlings are around 10 to 15 days old. They’ll be able to open their eyes and appear to have feathers, although it’ll be a little late. This starts a period in which the mother will be away from the nest for the most part of the day, as we previously mentioned. She’ll come back at least once an hour, if not more, to feed the infants. Before concluding that the mother is not returning, observe the nest for two hours straight.
- Return them to the nest if they’ve fallen from the nest. Handle with care. Make an artificial nest and set it nearby if the nest appears to be overrun with insects, such as ants, that may be injuring the infants.
- Watch the mother to make sure she returns to feed the baby birds after you put them back in the nest.
- Sugar water (nectar) may be given until a rehabber can take the birds if it has been determined that the nest is abandoned. Every 30 minutes, squeeze three drops of saliva into the baby’s mouth using a dropper. The birds’ feathers will get too sticky and matted if any nectar is spilled on them. It must be cleaned up right away. Do not feed nectar for more than 72 hours.
IF YOU FIND A PRE-FLEDGLING HUMMINGBIRD
Pre-fledglings (16 days old) are about to leave the nest and have their full feathers. They’re starting to investigate, and if they’ve fallen out of the nest, they’re usually discovered on the ground. Return the eggs inside the nest if you can see it, and wait for Mom to return.
- You may feed them 5 drops of nectar every 30 minutes until a rehabber can handle them if they are abandoned.
- Any nectar that gets on the birds will need to be cleaned off.
- Don’t offer nectar for more than 72 hours.
When seeking a local rehabber who can either offer you professional guidance or take the bird for treatment, you are providing emergency treatment to the bird. Letting trained personnel care for these young birds is crucial. Here are a few resources for locating rehab facilities in your area. However, these lists are seldom updated, and a search for “wildlife rehabilitation + your state” or visiting your state government’s department of wildlife may provide more reliable results.

Baby hummingbirds aren’t ready to feed themselves until they’re around 3-4 weeks old. Meanwhile, like she eats, her mother feeds them a mix of tiny insects and nectar. She’ll regurgitate food from her crop and feed them. The newborns spend the majority of their time alone, quietly snoozing in their nest while Mom visits only to drop off some food. Before you interfere on behalf of the birds, make sure that a nest has been abandoned. While speaking with a wildlife rehabilitator, give regular hummingbird nectar if necessary.
