The red siskin is under threat from illegal trapping for the cage bird industry, which has caused a rapid decline in numbers of this species over the last 150 years. Unfortunately, this bird is highly popular among breeders because of the fact that it can be successfully bred with canaries to produce a popular colourful hybrid (2).
Habitat degradation also poses a threat to this species, as potential nesting areas are converted for agricultural use. Captive breeding programmes of the red siskin have been set back by disease and hybrid stock (2).
The red siskin is also vulnerable to natural threats and, although no predation of the red siskin has been observed in the wild, 20 species of raptors living in the same habitat are thought to be likely predators of this bird. Due to the fact that its nests are located high in trees, predation by mammals is unlikely (7)
