Demography and Populations

The demography of the species is little known. For example, there is no information is available about the intervals between breeding for this species or the age of recruitment, as well as the population size and trends.

Age at First Breeding

Information is needed.

Intervals Between Breeding

Information is needed.

Clutch Size and Number of Clutches per Season

Between 2–4 eggs, but 4 egg clutches are regular (112 Maclean, G. L. (1972). Clutch size and evolution in the Charadrii. Auk 89:299–324. Close ; see also Breeding: Eggs). No information on the number of clutches per season.

Annual and Lifetime Reproductive Success

Information is needed.

Number of Broods Normally Reared per Season

Information is needed.

Proportion of Total Females that Rear ≥ One Brood to Nest-Leaving

Information is needed. However, BirdLife International (113 BirdLife International (2024). Species factsheet: Oreopholus ruficollis. Downloaded from http://datazone.birdlife.org/species/factsheet/tawny-throated-dotterel-oreopholus-ruficollis on 26/01/2024. Close ) estimated a generation length of 6.7 years.

Body Parasites

Endoparasites

The nematode Subulura huaynacapaci was reported in the small intestine of a Tawny-throated Dotterel collected in Trujillo, Perú (114 Freitas, J. F., J. J. Vicente, and H. N. Ibáñez (1968). Fauna helmintologia do Peru: Subulura huaynacapaci sp. n. (Nematoda, Subuluroidea). Atas da Sociedade de Biologia do Rio de Janeiro 12:85–86. Close ). The helminth parasite Oxynema sp. was also described in this species (115 Drago, F. B., V. Núñez, and M. D. Díaz (2020). Checklist of the nematodes of wild birds of Argentina. Revue suisse de Zoologie 127:43–46. Close ).

Ectoparasites

Chewing lice, including Quadraceps ruficollis and Actornithophilus ochraceus were reported on birds sampled in Argentina and Chile (116 Emerson, K. C., and R. D. Price (1985).

Direct Human Impacts

The Tawny-throated Dotterel was heavily hunted during their post-breeding migration in Chile and Argentina during the first half of the 1900s. Its numbers are thought to have declined considerably as a result (111 Philippi-Bañados, R. A., A. W. Johnson, J. D. Goodall, and F. Behn (1954). Notas sobre aves de Magallanes y Tierra del Fuego.

Numbers

BirdLife International (113 BirdLife International (2024). Species factsheet: Oreopholus ruficollis. Downloaded from http://datazone.birdlife.org/species/factsheet/tawny-throated-dotterel-oreopholus-ruficollis on 26/01/2024. Close ) estimated the global population as ranging between 670–6,700 mature individuals, although they considered the data quality poor.

Trends

The current trend is thought to be decreasing (113 BirdLife International (2024). Species factsheet: Oreopholus ruficollis. Downloaded from http://datazone.birdlife.org/species/factsheet/tawny-throated-dotterel-oreopholus-ruficollis on 26/01/2024. Close ). In the past, Tawny-throated Dotterel populations declined strongly, at least in some areas, likely as a result of hunting (111 Philippi-Bañados, R. A., A. W. Johnson, J. D. Goodall, and F. Behn (1954). Notas sobre aves de Magallanes y Tierra del Fuego. Boletín del Museo Nacional de Historia Natural 26:1–63. Close , 20 Wiersma, P. (1996). Family Charadriidae (plovers): species accounts.
