Table 1 Parameters entered in the procedure and values used for predictions of the timing of pre-nuptial migration

From: Modelling the timing of migration of a partial migrant bird using ringing and observation data: a case study with the Song Thrush in Italy

Name in the procedure

Description

Values used

StartD

Pre-nuptial migration: first day-of-the year for calculating cumulated ring encounters

Post-nuptial migration: last day-of-the year for backward calculation of cumulated ring encounters.

Pre-nuptial migration

1 December

6 December

11 December

Post-nuptial migration

20 November

25 November

30 November

NP

Minimum number of encounters in a cell

15, 20, 25

ND

Minimum number of different day-of-the-year for the encounters in a cell

Values are univocally defined according to NP values:

NP = 15 → ND = 7

NP = 20 → ND = 10

NP = 25 → ND = 15

NumDayLin

Minimum length of the linear phase

10

THR

Threshold value of the sum of absolute residuals of the linear regression of the left-hand part of the interpolated curve on time used to assess the end of the linear phase

0.05, 0.07, 0.1

PRED

Predicted proportion of individuals that have arrived used for model inversion

0, 0.01, 0.05, 0.1, 0.5
