Allen’s Hummingbird Male HS3268

Allen’s Hummingbird Male HS3283

Allen’s Hummingbird Male HS3293

The Allen’s Hummingbird is very similar to the Rufous Hummingbird, but with a green back and forehead.
The occasional green-backed Rufous Hummingbird is indistinguishable from the Allen’s in the field, and the
immature Allen’s Hummingbird is indistinguishable from Rufous females. Most identifications are made based
upon the breeding season and ranges. Most Allen’s Hummingbirds are found in brushy wooded areas north of
Santa Barbara, California to southern Oregon, but a group from Santa Barbara’s Channel Islands migrated
to the Palos Verdes Peninsula in southern Los Angeles in the 1960s and spread throughout the LA area.
The Rufous Hummingbird prefers open areas near the edge of forests, although they are migratory and
are often found in other areas. Allen’s and Rufous males have iridescent copper-red throat patches.

The green flecks on the forehead are visible in many of these images, making identification possible.
If a bird is seen during aerial display, their different display techniques will make identification easier.
The Allen’s begins the display by shuttling back and forth, then climbs to about 100 feet and makes a
screaming J-shaped dive, emitting a metallic whine from its wings during the dive. They occasionally
dive on people to chase them out of their territory. Believe me, the screaming whine is unmistakable.

The Rufous Hummingbird makes a series of slow climbs to J-shaped dives, but begins each dive at a
different point around an imaginary circle, emits a stuttering “dit”, and ends each dive at the same spot.

Male Allen’s Hummingbirds are extremely aggressive and very territorial. They will chase other males
and any other hummingbirds away from their chosen territory, and will also attack Kestrels and Hawks.

Anna’s Hummingbird Male HS2845 M

This series of images shows a perched Anna’s Hummingbird male at Sepulveda Wildlife Refuge.

These images presented a technical challenge, as the bird was sitting in the shade at mid-morning
back-lit against a bright blue sky. Capturing detail and color in the shaded areas of the face and helmet
while avoiding overexposure of the sky required dancing a fine line, and image processing was demanding.

Anna’s Hummingbird Male HS2877 M

Anna’s Hummingbird Male HS2882 M

1000 x 1590 pixel images of a backlit Anna’s Hummingbird male.

The Anna’s Hummingbird was named after Anna Massena, Duchess of Rivoli.

The Anna’s is a medium-sized hummingbird about 4 inches long, with an emerald green back
and sides, and a greenish-gray chest and belly. The male is the only North American hummingbird
which has a red helmet and gorget. Females and juveniles have a green head and a gray throat and
belly. Males have a forked tail, females and juveniles have rounded tails with white-tipped feathers.

Anna’s Hummingbird Female on Sage 2870 M

An Anna’s Hummingbird female, captured while hovering to feed on Mexican Sage.

The hummingbird flies close to the Sage and hovers, selecting an attractive opening while beating her wings
80 times per second. She then flits closer to drink nectar from the flower, backs out and selects another flower.
The hummingbird is the only bird which is able to fly backwards, which makes it possible to feed in this way.
Note the pollen atop the hummingbird’s bill. When she feeds, she pollinates flowers in return for her nectar.

Anna’s Hummingbird Female on Sage 2877

An Anna’s Hummingbird female hovers in front of a Mexican Sage, drinking nectar from its flowers.

Besides drinking nectar, the Anna’s Hummingbird is a carnivore, eating insects and spiders it finds
on the flowers for the protein they offer, as well as occasionally catching flying insects in the air. They
also will perch near a spider web to snatch the insects which get caught in the web. When they catch
an insect in the air, they will fly close to the insect and open their bill wide, snapping it down on the
hapless bug rather than skewering it on the sharp point. Every now and then, a hummingbird will
impale a bee or wasp on its bill though, and usually dies from starvation before it can free itself.

Anna’s Hummingbird Female 4126

Wing warp during hovering flight. A hummingbird’s wings beat up to 80 times per second, allowing them to hover in mid-air.

Anna’s Hummingbird Female 4127

Hummingbirds can fly as fast as 35 miles per hour, and are also the only known bird capable of flying backwards.

An Anna’s Hummingbird female captured in the process of transitioning from forward to hovering flight.
This series of flight images were taken at Indian Peak Ranch in Mariposa near Yosemite National Park.

Anna’s Male Hummingbird 1239 M

An Anna’s Hummingbird male also stopped by for an isolation portrait in front of the neutral background.
It is very rare to have an opportunity at a hummingbird in front of a neutral background in my experience.

Anna’s Male 2078

An Anna’s Hummingbird male perched in the shade of the Camellia Forest at Descanso Gardens.

In the soft light of the Camellia Forest, the spectacular color display of the Anna’s male gorget
draws the attention of any females in the area. Of course, this is not his only attractive feature.

Anna’s Male Display 2079

In case the brilliant color display is not enough, the hummingbird spreads his tail and wings.

Anna’s Male 2149

Anna’s Male 2153

Depending on the angle of the light, the colorful gorget can appear brown, rusty orange, purplish, crimson red or gold.

Anna’s Male 2154

Anna’s Male 2155

The Anna’s Hummingbird male moves his iridescent head
and stretches his neck to flash different colors from his gorget.

This male was quit adept at displaying the full range of colors, even in the soft, diffuse light.

Hummingbird Courtship

An Anna’s male attracts a female, and after doing his J-shaped mating dives, displays for the female,
who indicates her assent by closing her eyes. The female flies to a nearby branch, and the male zips over
and mounts her in flight. The entire mating event was over in a second and a half. The male immediately left.

Nesting Anna’s Hummingbird 0612c

A female Anna’s Hummingbird sitting atop her nest wedged into the fork of a tree.
The 2 inch diameter nest is built of twigs, lichen and moss, lined with feathers and hair,
and is bound together with spider silk, tree sap, and other sticky substances. The female
builds and attends the nest and raises her two chicks without the assistance of the male.
