Greater different kinds of birds
Yes , species with very small populations are at the verge of extinction as compared to large population .
There are approximately 10,000 bird species in the world. This number varies by a few hundred birds, depending on which classification system you use. Clements (now run by Cornell University) lists about 9,800 bird species whereas Sibley and IOU list over 10,000 species. As with most animal groupings, species are being redefined and what was considered to be one species may be split into two or more species, and in other cases. two species may be combined into one species. Clements is slow to make such changes. Splits and groupings of bird species happen regularly. It's even more common in butterflies and the taxonomy of moths is an even bigger mess! In the United States (including Hawaii) there are about 980 bird species, depending on the listing source.
In many species of birds, the female is the one who selects who she is willing to mate with. The female selects her mate based on who she thinks is the healthiest, strongest, etc. A male bird with more extravagent plumage compared to his peers has a greater chance of passing on his genes based soley on the fact that he appears to be healthier and a better mate.
In species such as mammals and birds the male species is typically larger than females. However, other than those the opposite occurs. In the majority of reptiles the females are larger than the males except lizards and crocodiles and most insects the female is larger than the males.
Yes, homosexuality is present in more than 1,500 species, including all species of mammals and birds, as well as many others, but homophobia is only present in humans.

It is 19 more than 152. 152 + 19 = 171
True
more than 1500, and still counting. We are still finding new species of plants, birds, reptiles, insects, etc. in the Amazon.
It depends on the rotation and revolution of the earth. In different seasons, different species of birds will fly more or less (both more or less frequently and in greater or lesser duration) than in other seasons. At different times of day, different species will be either awake or resting, making them more or less likely to be in flight.
Pioneers are healthier
Russa has over 300 species of mammals, more than 700 species of birds, about 40 species of amphibians, over 80 species of reptiles.
eagles have bigger beaks than huming birds
Vertical habitat and diversity.
The Nile Valley and Nile Delta
Actually, the rainforest supports the greatest number of species of plants and animals. The grasslands support a greater variety of species than the desert.
The 45 species of Antarctic birds tend to have...Thick inner down feathers for warmthOily and waterproof outer feathersA greater proportion of tendons to muscles (muscles lose heat more quickly than tendons),Black, grey, white, and brown colors for camouflageShort tails and extremities to minimize heat lossAntarctic breeders use stones rather than vegetation for nestsAll birds in the Antarctic rely on the ocean for food, and all 45 species swim or dive to some degree.
