Methods Population surveys
Bächler, E. (erich.baechler@vogelwarte.ch), Liechti, F. (2007). On the importance of g(0) for estimating bird population densities with standard distance-sampling: implications from a telemetry study and a literature review. Ibis 149(4): 693–700. When using distance sampling methods to survey pigeon populations it is not always possible to use straight transects. A solution is offered by: Weather conditions and bird surveys: Santos, M. (mgsantos “at” utad.pt), Travassos, P., Repas, M. and Cabral, J.A. (in press) Modelling the performance of bird surveys in non-standard weather conditions: General applications with special reference to mountain ecosystems. Ecological Indicators (Woodpigeon Columba palumbus). To help design a precise index to population abundance, USGS scientists examined the effectiveness of existing survey methods in detecting long- and short-term population changes in the Band-tailed Pigeon Patagioenas fasciata. Research results have indicated 1) three- to five-year trends were most reliably estimated using counts conducted at mineral sites where pigeons congregate, 2) the importance of weather (rainfall) on the surveys, and 3) the importance of adjacent forestland and human use of mineral sites on the likelihood of persistent use by band-tailed pigeons.

Satellite tracking Scientists at Oxford University, UK have used precision GPS technology to track pigeons along their homeward routes to determine whether they use visual cues along the homeward flight over terrain they had previously flow over:
