Timing of flights in displaced (blue) and control (red) adult (light) and young (dark) cuckoos. Displaced and control young were tracked for equally long (day of the year of last position: 289.3 ± 35.9 and 319.0 ± 47.7 [mean ± SD] for displaced (n = 8) and control young (n = 4), respectively; t₁₀ = 1.22, p = 0.25; Day of the year of last position adults: 288.5 ± 24.7 and 307.3 ± 37.3 for displaced and control adults, respectively). The tracks were terminated for four out of the eight displaced juvenile cuckoos already in September and for the displaced adults in the end of September and early October.
