We compared the occurrence and density of an Endangered habitat specialist, the forty-spotted pardalote (Pardalotus quadragintus) with those of a common habitat generalist, the striated pardalote (Pardalotus striatus). This kind of comparison is valuable in systems where a generalist and a specialist coexist and share resources, since habitat disturbance can lead to higher competition, and specialists are known to be more vulnerable to changes in their environment. Our study reveals that, although widespread, the generalist pardalote is most abundant in the limited areas of habitat suitable for the specialist, and this indicates the need of future research to look at whether this pattern of occurrence exacerbates competition between them in resource-depleted habitats.
