Figure 1. District-level map of Bangladesh showing the number of surveyed Red-necked Falcon Falco chicquera pairs, throughout the year between 2002 and 2019.
Table 1. Red-necked Falcon Falco chicquera prey species, derived from long-term field observations between 2002 and 2019, with mean prey weights (g) in Bangladesh. N = number.
Figure 2. Seasonal changes in mean prey weight (g) and the proportion of birds (white bars) and bats (grey bars) in the diet of Red-necked Falcons Falco chicquera in Bangladesh between 2002 and 2019. Error bars = 95% confidence intervals, N = sample sizes.
Table 2. GLMM parameters and contrasts exploring seasonal changes in the probability of bats (Chiroptera spp.) in the diet of Red-necked Falcons (Falco chicquera) in Bangladesh between 2002 and 2019. SE = standard error and df = degrees of freedom.
Figure 3. Seasonal changes in the probabilities of Red-necked Falcons Falco chicquera being mobbed while feeding by the most common species, i.e. ≥ 30 observations: (a) House Crows Corvus splendens (N = 358), (b) Black Kites Milvus migrans (N = 170), (c) Red-necked Falcons (N = 84), (d) Black Drongos Dicrurus macrocercus (N = 33), and (e) Large-billed Crows Corvus macrorhynchos (N = 31) in Bangladesh between 2002 and 2019.
Table 3. Observed inter- and intraspecific mobbing events during Red-necked Falcon Falco chicquera feeding activities in Bangladesh between 2002 and 2019. Species presented above the dotted line represent the most common mobbing species, i.e. those with ≥ 30 observations, and were used in statistical analyses.
