What type of birds have long thin beaks?
Well, hummingbirds have long thin beaks for their size. They are from the family Trochilidae which is categorized of different sorts of hummingbirds. Another bird with long beaks are woodpeckers, to get worms.
Depending on the type of bird, long-billed species typically eat fish and crustaceans or insects. Their bills are specially formed to be able to reach into small holes in trees or into sand and silt underwater. If you think about it, birds with this type of diet do not need short strong beaks like those that need to break open seeds.
9 Responsive evolution involves organisms evolving in tandem to improve chances of survival An example of this type of evolution is?
There are countless examples of this type of evolution, but I will give you one; Humming birds and the elongated pouches of the flowers they eat from; If the flower already has a long pouch, and a bird who's diet is of nectar but doesn't have a long beak, birds with longer beaks will get to eat more, thus it will be healthier and get to pass it's genes on. While the flowers that don't…
Primarily because they have beaks adapted to a specific type of food. There are triangular bills for opening seeds, pointed bills for spearing fish, scissor-like bills for tearing meat, gaping bills for catching flying insects, all-purpose bills for eating a variety of foods, probing bills for extracting insects in the mud or nectar from flowers, chisel-like bills for drilling into wood, and others.
These birds, although nearly identical in all other ways to mainland finches, had different beaks. Their beaks had adapted to the type of food they ate in order to fill different niches on the Galapagos Islands. Their isolation on the islands over long periods of time made them undergo speciation (form new species). Darwin wrote about his travels in the book The Voyage of the Beagle and fully explored the information he gained from the…
The scapula is an irregular bone, and is defined as such because it is not a long, short, or thin bone. A long bone is longer than it is wide, for example the femur. Short bones are "cube shaped", such as the cuboid (one of your tarsal bones). Thin bones have a curve to them and are fairly flat, such as your sternum.
