Ten Facts about Birds
- Most bird species use different vocalizations for different circumstances.
- Birds have unique digestive and respiratory systems that are highly adapted for flight.
- Currently about 1,200 species of birds are threatened with extinction by human activities.
- All living species of birds have wings - the now extinct flightless Moa of New Zealand were the only exceptions.
- The highest bird diversity occurs in tropical regions.
- Birds have one of the most complex respiratory systems of all animal groups.
- Bird species migrate to take advantage of global differences of seasonal temperatures, therefore optimising availability of food sources and breeding habitat.
- Birds communicate using primarily visual and auditory signals. Signals can be interspecific (between species) and intraspecific (within species).
- Ninety-five percent of bird species are socially monogamous.
- Birds do not have a urinary bladder or external urethral opening and uric acid is excreted along with feces as a semisolid waste (with exception of the Ostrich).
