Do hummingbirds like to drink water?

Hummingbirds are well known for their ability to hover and fly backwards, as well as for their rapid wing beats and high metabolism. But one thing many people may not know about these tiny birds is that they get most of the water they need from flower nectar and plant sap, and don’t actually need to drink much water at all.

Do hummingbirds drink water?

The short answer is yes, hummingbirds do drink water. However, they get most of their hydration from the nectar and sap they eat. Here are some key points about hummingbirds and water:

• Hummingbirds have adapted to get most of their water intake from the nectar and sap they feed on. These fluids are anywhere from 25% to 60% water.
• They will drink water from bird baths, dripping faucets, waterfalls, and other sources, especially in hot or dry conditions when their food sources may not provide enough hydration.
• Water makes up only a small percentage of a hummingbird’s overall diet. One study found only about 11% of a hummingbird’s diet is water from non-food sources.
• Hummingbirds can get all the water they need from their food without drinking extra water. But they will readily drink water when it is available as an extra source of hydration.

So in short, yes hummingbirds do drink water at times, but they rely much more heavily on the water content from nectar and sap than direct water sources. Their specialized diet and feeding habits provide most of the hydration they need to survive.

Why don’t hummingbirds drink a lot of water?

There are a few key reasons why hummingbirds get most of their hydration from food instead of drinking water directly:

• High energy needs – Hummingbirds have extremely high metabolisms and energy needs. They must eat almost constantly throughout the day to get enough calories and nutrients to power their rapid heartbeats, wing beats, and activity levels. Eating nectar and sap maximizes their energy and nutrient intake in a small amount of liquid.
• Small body size – Weighing only 2-20 grams, hummingbirds are very small. They cannot store large amounts of water or energy reserves. Their small size requires them to rely on food sources that provide a concentrated mix of calories and water.
• Specialized diet – Hummingbirds’ long slender beaks and tongues are perfectly adapted for accessing the nectar and sap of certain flowers and trees. This unique adaptation allows them to obtain both calories and water very efficiently through their specialized diet.
• Minimizes time spent not feeding – Hummingbirds need to feed frequently throughout the day. Getting water directly from food sources minimizes the time they would otherwise spend seeking out water and not feeding.

By getting both water and nutrition from nectar and sap, hummingbirds maximize their survival efficiency given their incredibly high energetic demands, small size, and specialized feeding adaptations.

When and why do hummingbirds drink water?

Though they don’t drink water constantly like some other birds, hummingbirds will drink water in certain situations when they need extra hydration:

• In hot, dry conditions when their food sources may not provide enough water
• After eating dry pollen, which can be dehydrating
• When fresh water sources like dripping taps or waterfalls are readily available
• During long flights over dry terrain when they burn more energy and lose more water through respiration

Drinking extra water helps hummingbirds maintain fluid balance and prevents dehydration when their food sources or environmental conditions result in extra water loss. While not necessary on a regular basis, extra water helps hummingbirds stay energized and healthy when conditions are hot, dry, or water-depleted.

What sources of water do hummingbirds drink from?

When hummingbirds do opt to drink, here are some common natural and human-made water sources they will use:

• Bird baths
• Backyard water features like fountains or drippers
• Streams, lakes, and other natural water bodies
• Waterfalls and seeps
• Leaky outdoor faucets and irrigation systems
• Rain and dew collected on leaves and branches
• Sap wells drilled by sapsuckers

Hummingbirds are attracted to shallow water sources they can easily hover over and dip their beaks into. Moving water from drippers, seeps or waterfalls is especially enticing, as it creates little glints of light that catch their attention. Placing bird baths or drippers near hummingbird feeding areas will encourage them to stop for a drink while feeding.

Do hummingbird feeders need to include water?

There is no need to add water to hummingbird feeders. The nectar or sugar water you put in the feeders provides hummingbirds with their hydration needs. Adding open sources of water may actually promote bacterial growth in the feeder and spoil the nectar faster.

However, you can provide a separate bird bath, fountain, or mister in your yard to give hummingbirds the option of drinking fresh water when they choose. Just be sure to place it far enough away from the feeder to avoid contamination between the two water sources.

Signs that hummingbirds are drinking water:

Here are some ways to tell when a hummingbird is drinking water at a bird bath, fountain, or other source:

• It will hover in place over the water for several seconds at a time.
• You may see its beak dipping repeatedly into the water.
• Its throat will pulsate as it drinks.
• You may hear it making squeaking or clicking sounds while drinking.
• Watch for water droplets on its beak and head feathers after drinking.

Observing hummingbirds stop to drink is a great chance to see these energetic birds at rest for a moment. Providing clean, fresh water sources can give them the extra hydration they need while giving you an opportunity to watch their fascinating drinking behavior up close.

How much water does a hummingbird drink?

According to various research studies on hummingbird water balance and intake:

• Water can account for 11-25% of a hummingbird’s total daily fluid intake.
• During a day, a hummingbird may drink approximately 0.2-0.3 grams of water on average.
• In hot conditions or after eating dry pollen, water intake may increase to over 50% of their fluid intake for that period.
• In comparison to their small body size, a human would have to drink over 6 gallons of water a day to stay as hydrated as a hummingbird.

Considering their tiny size, hummingbirds are able to take in impressive amounts of fluid each day from both food and drink. Careful monitoring of their high energy demands and food availability allows them to stay properly hydrated.

Tips for providing water for hummingbirds:

Here are some tips for providing clean, enticing water sources to attract hummingbirds:

• Use shallow bird baths, drippers, or fountains no deeper than 1-2 inches so hummingbirds can easily sip.
• Refill water sources frequently, or use moving water to prevent bacterial growth.
• Place water sources out of direct sun to prevent algae growth and keep water cool.
• Add stones or pebbles for perches so the birds can easily come and go.
• Move water sources near feeders during hot spells when birds need more hydration.
• Misting vegetation is another great way to provide water via transpiration.

With a little thoughtful placement and care, you can provide natural, clean water sources that will attract hummingbirds and offer them hydration as they need it.

Interesting facts about hummingbirds and water:

• A hummingbird’s kidneys can process up to 25 times more fluid than a human’s relative to its size.
• Hummingbirds can die within hours if deprived of food and water.
• Hummingbirds have been observed drinking rain by flying through the air with their beaks open.
• Young fledgling hummingbirds get water from dew and raindrops collected in bromeliad plants.
• Some tropical hummingbird species get water from spiderwebs when other sources are scarce.

Hummingbirds have evolved some amazing adaptations for getting the water they need in a range of conditions. Their flexibility in water sources allows them to thrive in diverse habitats from tropical rainforests to hot deserts.

Conclusion

In summary, while hummingbirds fulfill most of their needs for hydration through flower nectar and plant sap, they will also drink from water sources as extra hydration when needed. Providing clean bird baths, drippers, or misters in your yard is a great way to give hummingbirds the supplemental water they may seek out, especially in hot, dry conditions. Understanding how hummingbirds meet their hydration needs gives us insight into their specialized adaptations for harnessing energy and thriving in diverse environments.
