The first stamp, issued in 1995, shows a great horned owl (Bubo virginianus), which has been discussed in the past. The stamp below it belongs to the same set and shows a Rivoli's hummingbird (Eugenes fulgens) feeding on nectar. It is found in the southwestern United States and in Central America and it is migratory. It has no subspecies. It is also sexually dimorphic with males being slightly larger than females and having a shorter beak. Males also have a purple crown and green chest. The females lack the purple crown and their chest is grey.

The last two stamps, also issued in 1995, depict the American pigmy kingfisher (Chloroceryle aenea) to the left and the green kingfisher (Chloroceryle americana) to the right.

The American pigmy kingfisher can be found in Central and South America. It has two subspecies. Females have a dark green band of feathers on their upper chest while males lack it. It feeds on small fish, frogs, tadpoles and large insects.

The green kingfisher can be found in the southern United States (mainly Texas), Central America and northern and central South America. It has five subspecies. The male, which is depicted on the stamp,  has a red chest while the female lacks any red colouration. Finally, they feed on small fish, shrimps and insects.
