   FIG. A1. Photographs of bills of E. jugularis (A and B), flowers and inflorescences of Heliconia species (C to H) on St. Lucia, West Indies, orientation of the birds during feeding visits to heliconias (I and J), and measurements of bill and flower chords and angles (K and L). (A) E. jugularis, female bill. (B) E. jugularis, male bill. (C) Green-bracted morph of H. bihai, flower. (D) Red-green bracted morph of H. bihai, flower. (E) H. caribaea, flower. (F) Green-bracted morph of H. bihai, inflorescence. (G) Red-green bracted morph of H. bihai, inflorescence. (H) H. caribaea, inflorescence. (I) Female E. jugularis feeding from a flower of the green-bracted morph of H. bihai; note that the bird inverts its head to feed. (J) Male E. jugularis feeding from a flower of H. caribaea; the near side of the bract has been removed to make the flower and bill visible. (K) Bill of female E. jugularis illustrating chord (i; length of exposed culmen) and angle (ii) measurements. (L) H. bihai flower illustrating chord (i) and angle (ii) measurements.
