Host acquisition by Ornithodoros capensis Neumann (Ixodoidea: Argasidae)

|January 1, 1981
Summary
Forty percent of white-capped noddy tern nests were re-occupied the next season. This nest reuse facilitates parasite transmission during the non-nesting period.
Area of Science:
- Ornithology
- Ecology
- Parasitology
Background:
- Avian nesting behavior is crucial for reproduction and species survival.
- Nest reuse by subsequent bird generations can influence disease and parasite dynamics within a population.
Purpose of the Study:
- To investigate the rate of nest re-occupation by white-capped noddy terns.
- To understand the ecological implications of nest reuse, particularly for ectoparasite survival and transmission.
Main Methods:
- Marking and tagging of white-capped noddy tern (Anous minutus) nests.
- Monitoring nest occupancy during consecutive nesting seasons (1977 and 1978).
Main Results:
- Forty percent of tagged nests were re-occupied in the subsequent nesting season.
- The persistence of ticks (Ornithodoros capensis) within abandoned nests was observed.
Conclusions:
- White-capped noddy terns exhibit significant nest re-occupation rates.
- Nest reuse provides a mechanism for the survival and host acquisition of Ornithodoros capensis ticks between breeding seasons.
