Clobert J., Lebreton J.D. & Allaine D. (1987) A general approach to survival rate estimation by recaptures or resightings of marked birds. ARDEA 75 (1): 133-142
A general approach to survival rate estimation by recaptures or resightings of marked birds is presented. This approach permits to generate any models involving age and/or time dependence in survival and/or capture rate. Models involving equality between subsets of parameters are also described, as well as models relating survival rate or capture rate with one or several external variables. The estimates can also be constrained between 0 and 1 or the parameters fixed to a priori values. Two examples, one on the Great Tit and one on the Black-headed Gull, are given to illustrate this approach. A Fortran 77 computer program allowing fitting these models is available from the authors.
