Table 3 Summary of the optimal models predicting the activity intensity of Great Knots before sunset based on data from orientation funnels at two stopover sites (CMDT in the south Yellow Sea and YLE in the north Yellow Sea)

From: Springtime migratory restlessness and departure orientation of Great Knots (Calidris tenuirostris) in the south compared to the north Yellow Sea

  1. The estimated coefficients (mean ± SE) for the variables were calculated according to their beta estimates and AIC weights of the competitive models (Additional file 1: Table S1) (Burnham and Anderson 2002). The significant levels for the estimated coefficients of the included parameters are listed (*** < 0.001; ** 0.001–0.01; * 0.01–0.05; – not involved)
