Figure 4 in Review of the breeding biology of rufous crab hawk Buteogallus aequinoctialis (Aves: Accipitridae) across its distribution

Figure 4. Relative frequencies, per month of the year, of Buteogallus aequinoctialis breeding records. (a), Venezuelan records; (b), records from the Guianas; (c), Brazilian records. Horizontal lines referred to as 'Breeding season' depict literature information on breeding seasonality (either relying on egg dates, or indeterminate); respective sources are – from top to bottom – Hellebrekkers (1942); Snethlage (1928); and Ferguson-Lees and Christie (2001). The right-pointing arrow in the bottom graph represents the uncertain extent of the season ('September onwards').
