From: Effects of radio-tag characteristics and sample size on estimates of apparent survival
The re-encounter probabilities ( p ) in relation to time after fledging as calculated using the full sample. Transmitter specifications and cohort sizes are given in Table 1. Color-marked birds were not recovered regularly after family break-up, that is, 12 to 15 days after fledging. The life of a 35 μW tag was less than 20 d. Trend lines were fitted by distance-weighted least squares, except for color marks (linear trend).
