What are the most interesting facts about the Rufous Hummingbird?
The Rufous Hummingbird is renowned for its impressive migration, travelling up to 3,000 miles each way between Alaska and Mexico. These tiny birds, weighing only 2-5 grams, are known for their aggressive behaviour and can fly backwards and hover by beating their wings up to 62 times per second.
1. Size and Appearance
The Rufous Hummingbird is one of the smallest hummingbird species, measuring a mere 7-9 cm (2.8-3.5 inches) in length. To put this into perspective, they’re about the size of a ping-pong ball! Despite their diminutive stature, these birds are easily recognisable thanks to their vibrant colouring.
Male Rufous Hummingbirds sport a bright orange-red throat patch, known as a gorget, which gleams brilliantly in the sunlight. Their backs and tails are adorned with a rich, rufous (reddish-brown) colour, giving them their name. Females, on the other hand, are more subdued in appearance, with mostly green plumage and touches of rufous on their flanks and tail.
2. Record-Breaking Migration
Perhaps the most astounding fact about the Rufous Hummingbird is its incredible migration route. These tiny birds undertake one of the longest migrations of any bird relative to their body size. They travel up to 3,000 miles each way between their breeding grounds in Alaska and western Canada and their wintering grounds in Mexico.
This journey is equivalent to flying from London to Cairo and back again – twice! It’s an impressive feat for any bird, but especially remarkable for one that weighs less than a 20p coin.
3. Aggressive Behaviour
Don’t let their small size fool you – Rufous Hummingbirds are known for their feisty and aggressive nature. They’re often seen chasing away much larger hummingbird species from feeders and flowers. This territorial behaviour helps them secure the best feeding spots, which is crucial for their survival, especially during migration.
Their aggressive tendencies have earned them nicknames like “the feathered fury” among birdwatchers and researchers. It’s not uncommon to see a Rufous Hummingbird fearlessly taking on birds several times its size in territorial disputes.
4. Unique Flight Abilities
Like all hummingbirds, the Rufous possesses some truly remarkable flight abilities. They can:
- Fly backwards
- Hover in mid-air
- Fly upside down for short distances
- Beat their wings up to 62 times per second.
These incredible aerial manoeuvres are made possible by their unique wing structure and powerful flight muscles. The rapid wing beats create the characteristic humming sound that gives hummingbirds their name.
5. Big Appetite
To fuel their high-energy lifestyle and maintain their rapid metabolism, Rufous Hummingbirds have a huge appetite relative to their size. They can consume close to half their body weight in food each day!
Their diet consists primarily of nectar from flowers, which they extract using their long, specialized tongues.
However, they also feed on small insects and spiders for protein, especially during the breeding season. This combination of sugary nectar and protein-rich insects provides the perfect balance of nutrients for these tiny dynamos.
6. Excellent Memory
Despite their small size, Rufous Hummingbirds possess remarkable cognitive abilities, particularly when it comes to memory. They can remember the locations of feeders and flowers from previous years, allowing them to efficiently find food sources during their long migrations.
This impressive memory also extends to the timing of when certain flowers bloom along their migration route. By remembering these details, they can plan their journey to coincide with the availability of food sources, ensuring they have enough energy for their long flight.
7. Nesting Habits
Female Rufous Hummingbirds are responsible for building the nests and caring for the young. They construct tiny, cup-shaped nests about 2 inches in diameter on tree branches. These nests are marvels of avian architecture, made from plant down, spider silk, and lichen.
Interestingly, females often reuse old nests, either renovating their own from previous years or commandeering those built by other hummingbird species. The typical clutch size is two eggs, which are about the size of coffee beans.
8. Northernmost Breeding Range
The Rufous Hummingbird holds the distinction of breeding farther north than any other hummingbird species. Their breeding range extends all the way up to south-central Alaska, making them true pioneers of the hummingbird world.
This northerly breeding range is part of what necessitates their long migration. By breeding so far north, they can take advantage of the long summer days and abundant insect populations in Alaska and western Canada.
9. Torpor: Energy-Saving Superpower
To conserve energy during cold nights or when food is scarce, Rufous Hummingbirds can enter a state of torpor. This is a type of short-term hibernation where they lower their body temperature and slow their heart rate and breathing.
During torpor, a hummingbird’s heart rate can drop from over 1,000 beats per minute to fewer than 50, and its body temperature can fall by as much as 50°F. This remarkable ability allows them to survive in conditions that would otherwise be too challenging for such a small, high-energy bird.
10. Conservation Status
In 2018, the Rufous Hummingbird was uplisted from Least Concern to Near Threatened on the IUCN Red List.
This change in status is due to observed population declines, which are likely related to climate change impacts and decreases in insect populations.
The Rufous Hummingbird’s long migration makes it particularly vulnerable to changes in habitat and food availability along its route. Conservation efforts are now focusing on protecting key stopover sites and educating the public about the importance of maintaining native plant species that these birds rely on for nectar.
Final Thoughts
The Rufous Hummingbird truly embodies the phrase “good things come in small packages”. From their incredible migration feats to their fiery personalities, these tiny birds never cease to amaze. Their ability to adapt and survive in challenging conditions is a testament to the resilience of nature.
As we face increasing environmental challenges, the plight of the Rufous Hummingbird serves as a reminder of the delicate balance in our ecosystems. By learning about and appreciating these remarkable birds, we can be inspired to take action to protect them and their habitats.
