Broad-billed Hummingbirds Cynanthus latirostris are found primarily in northwestern Mexico. They do occasionally range into southern Arizona, southwest New Mexico and west Texas in the spring and summer. They are also occasionally reported in Southern California.
Terres ;US Distribution and Abundance They tend to cynznthus and nest in areas such as canyons, foothills and streambeds. Their distribution in any particular area is closely tied to the availability and abundance of appropriate food plants. Broad-billed Hummingbirds are considered a small hummingbird. Their average length is 8. The males weigh about 3. Broad-billed Hummingbirds have a bright red bill with a black tip.
The adult males have metallic green bodies, vibrant blue throats, white undertail coverts and black forked tails. The adult females have metallic green upper parts and grayish throats and undersides. Their tails have pale outer tips. Most distinguishing about the female is the thin white spot latitostris her eye.
The method in which hummingbird wings are attached to the shoulder allows the wings to move in various angles, enabling the hummingbird to hover, fly straight up, sideways, and even backwards. This unique method of flight requires large flight and pectoral muscles, which weigh about 30 percent of their body weight.
The hummingbird’s wing beat is approximately beats per second Page and Morton ; Sayer ; Terres Breeding season is closely tied to the flowering season of some plants.
Broad-billed Hummingbirds are polygynous, meaning that males have more than one mate at the same time. Males who defend a territory are more successful than “floaters” those without a territory at attracting females. The males attract females with songs, and their songs tend to be very simple in design.
When the female respond to the advertising male, it usually results in copulation. The female then builds the nest. The nests are mainly built in trees or large scrubs approximately 1. Material used to make the nests may include grasses, leaves, bark and other plant material. Once the nest is complete, the female will lay one to two elongated, white eggs. She incubates the eggs from days, and rears the young without the assistance of the male.
Campbell ; Martin ; Perrins ; Sayre ; Terres In general, aggressive behavior of hummingbirds includes threat vocalizations, dives, and chasing of intruders. Most aggressive behavior is associated with territorial defense.
Male hummingbirds typically defend feeding territories as well as breeding sites, and females defend nesting sites. A large percentage of the male’s time and energy is used to defend his territory. Such defense usually begins in the air. It can include clawing, pushing, even using their bill as a weapon.
It was believed at one time that hummingbirds sucked the nectar through their bills. It is now proven that they use their forked-tongue to lap nectar from flowers. Many kinds of hummingbirds sometimes enter into short states of torpor, which is used to conserve their energy and lower their metabolism.
This usually happens when the night temperature is low or if the hummingbird has low food reserves. The average body temperature of the hummingbird is 41 degrees Celsius degrees Fahrenheit. During torpor, a hummingbird’s body temperature will lower to about the same temperature as the air. Hummingbirds in this state can appear dead. Their metabolism rate is so reduced that they may actually stop breathing for a short period of time Perrins ; Sayre The diet of the Broad-billed Hummingbird is primarily nectar from flowers such as the red blossoms of Ocotillo and Paintbrushes.
They eat sugar-water from hummingbird feeders as well.
Because of their metabolic rate, it is not uncommon for them to eat five to ten times an hour. Broad-billed Hummingbirds also need protein; therefore they are known to eat many insects such as aphids, leafhoppers, bugs, and root gnats. Hummingbirds will consume more water in a day than solid foods Sayre ; Terre Broad-billed Hummingbirds pollinate many flowers. As a result, this helps to support the ecomonic growth of the ornamental horticulture industry. Page and Morton In the nineteenth century, hundreds of thousands of hummingbirds were killed in South America and sent to England to be used as decorations.
Some individuals would have the colorful birds stuffed and placed on display in their homes. Many were used in the design and decoration of women’s hats. It has been reported that up toskins were imported in a single year by one London dealer. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico.
Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria.
Found in coastal areas between 30 and 40 degrees latitude, in latirostrsi with a Mediterranean climate. Vegetation is dominated by stands of dense, spiny shrubs with tough hard or waxy evergreen leaves. May be maintained by periodic fire.
In Lagirostris America it includes the scrub ecotone between forest and paramo. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry.
This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by latirostrie influence of salt in the air and soil.

Salt limits the ability of plants to take up water through their roots. Endothermy is a synapomorphy of the Mammalia, although it may have arisen ltirostris a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities. Iteroparous latiroostris must, by definition, survive over multiple seasons or periodic condition changes.
