The conservation of highly mobile species presents challenges to managers
for assessment of threats to survival, given the difficulties in locating
and observing such species. Here we evaluate satellite telemetry, DNA
faecal metabarcoding and traditional field observations as three
complementary techniques to acquire critical management information for an
endangered species, Carnaby's Cockatoo Calyptorhynchus latirostris.
Satellite telemetry of 23 birds resulted in 6026 location fixes accurate
to within 500 m, and combined with extensive field observations and DNA
faecal metabarcoding resulted in a more detailed understanding of how this
species survives in an urbanised landscape. We identified 168 night
roosts, 75% of which were previously unknown, which will contribute
towards a more accurate population size estimate based on annual counts of
roosting birds. We also determined the scale of daily movements (morning
5.4 ± 3.4 km from roost, afternoon 5.5 ± 3.3 km to roost; maximum distance
between consecutive roosts 69.7 km) and the size of foraging areas around
roosts (range 17 to 276 km2), and identified dependence on a variety of
native and exotic food sources. Field observations identified 11
food-plant families, but combined with DNA faecal metabarcoding this was
extended to 21 food-plant families. The three techniques were compared to
assess their individual and collective values. By combining spatial
ecology information from satellite telemetry with ecological knowledge
from field observation and DNA faecal analysis, we gained deeper insights
into the ecology of the species than would have been possible from any one
technique alone. This information will lead to more strategic conservation
planning to allow this species to persist within a rapidly expanding urban
environment.
