Why You Need An Avian Veterinarian

Unfortunately, many people forgo taking their bird to the vet until it is too late, as in, “Now I should take my bird to the vet because it is down on the bottom of the cage.” When a bird is that sick, it is very difficult (for anyone, no matter their knowledge or expertise) to bring the bird back from the brink of death.

Anatomy of the Avian Heart

The most striking features of birds is their ability to perform very rigorous functions in harsh environments, such as diving deeply in cold water, flying at high altitudes and running in hot deserts. This requires that their cardiovascular system (CVS) be able to meet the demands of providing adequate delivery of oxygen to vascular beds that are taxed by extreme metabolic demands.
