hey guys this is my animal project. we made bird housesin science class and i made one for hummingbirds so here is the written copy of my work.:)

humming birds:

What is the organisms common name and scientific name?
     common name: ruby throated hummingbird scientific name: Archilochus colubris

What does the organism look like? Is there a difference between male, female and  juvenile?
Ruby-throated hummingbirds are bright emerald or golden-green on the back and head, with gray-white belly. They also have a long, straight, thin bill. The male ruby-throated hummingbird has red throat, but the female does not.

      ,    What is the average height and size of an adult?
weight: 0.07 to 0.21oz (2 to 6 g) size: 3 to 4 in (7 to 9 cm)
Adult females are 15-20% larger than adult males

What type of habitat does the organism need?
Eastern North America. in deciduous and pine forests. nest along forest edges, in orchards, and in gardens where flowering plants are plentiful

       What role does this organism play in food chains in the ecosystem? (Include predator &             
      prey, or food preference for herbivores as applicable)
are important pollinators, especially of deep-throated flowers.
While ecologically the role of hummingbirds as pollinators and insect controls is of great importance

      Describe behaviours of your organism?mating, song or physical adaptations

Hummingbirds communicate with one another by making visual displays. Males sometimes raise the feathers bordering the gorget and toss their heads from side to side, while uttering shrill sounds. Females and young are more likely to do perched displays in which they spread their tail feathers to show the white tips. Male and female hummingbirds establish separate territories--she to build a nest and feed her young, he just to protect a reliable food source. The male takes no interest in nests or the care and feeding of babies. When females enter his territory, he does aerial displays to keep them away hummingbirds compete for nectar and insects. They guard their territories fiercely, perching high near flowering bushes or feeders

Describe the nesting behaviour of the organism.
Only female hummingbirds build nests.the perfect spot is typically on a downward slanting branch of a big tree or shrub, about 3 to 33 feet above the ground. they lay their eggs in the nest and raise their young. apparently two is the optimal number of chicks the female can care for.Chicks are in the nest for almost three weeks.When the chicks finally leave the nest, they are completely grown and are able to take care of themselves.
