Figure 3 in Breeding in the gray-headed tody-flycatcher (Aves: Tyrannidae) with comments on geographical variation in reproductive traits within the genus Todirostrum

Figure 3. Results of the generalised linear model between: (a) precipitation seasonality and clutch size; (b) temperature seasonality and clutch size; and (c) latitude and clutch size for six species of Todirostrum. (d) Correlation between latitude and length of the breeding season for three species of Todirostrum. Clutch sizes were averaged for each species and locality. Data on the length of breeding season are from: Hellebrekers (1942), Skutch (1951), Haverschmidt (1968), Thomas (1979), Marceliano (1982), Ramo and Busto (1984), Cruz and Andrews (1989), Stiles and Skutch (1989), Verea et al. (2009), and this study. Points are semi-transparent due to overplotting.
