Factors significantly related to the activity intensity (log-transformed scratch numbers) of Great Knots recorded in orientation funnel cages before sunset at CMDT and YLE. According to the AICc value of all the candidate models (Additional file 1: Table S1), the best model for bird activity intensity includes only the wind effect at CMDT (a) while includes test date (b), body mass decrease (c), and wind effect (d) at YLE. Adjusted activity intensity is shown for data at YLE to exclude the influence of factors other than the presented one. Additional details are provided in Table 3
