WEC267: Florida's Introduced Birds: Sacred Ibis (Threskiornis aethiopicus)

Figure 5. Native Wood Storks (A) have a much more erect stance when seen in silhouette, and only the tip of the bill is curved. Sacred Ibises (B) and native White Ibises (C) both have bills that are curved along the entire length and have similar silhouettes, but invasive Sacred Ibises are much larger than the native ibis.
