Two species are considered Endangered, facing a very high risk of extinction, and five have been described as Vulnerable, facing a high risk of extinction. One of these, the streak-breasted bulbul, is native to four different Philippine islands and has lost much of its habitat. Even though it does live in open areas, under some circumstances forests also appear to be necessary for its survival. In addition to protecting habitat, further study of the birds' behavior is necessary so we can fully understand what they need to continue to survive.
