Figure 1. I was trying to attract a woodcreeper with playbacks, when this hawk suddenly landed on a tree branch a few meters above me, apparently searching for the fictive woodcreeper. It stayed there for half a minute, looking in all directions. This gave me time to take a few photos.

For details of head, see fig. 2.

Figure 2. Details of head. Same individual as above.

Figure 3. A few seconds after I took the pictures shown above, the hawk took off, and this was the last photo.

Compare with:
Mata et al. 2006, p. 124/125;
Hilty and Brown 1986, pl. II/2.

Figure 4. This picture shows the short tail of the Short-tailed Hawk in some detail. The tail feathers are barred, with a variable number of visible bars (6 on the outermost feather, 3-5 on the others). This does not match the description in Mata et al. 2006, "...Tail with 3 black bars and broad subterminal band" (p. 124) or in Meyer de Schauensee 1970: "...two narrow, and one broader ... band" (p. 44). Restall et al. 2006a,b counted "5 black bars on dark grey tail".
