These are the best months of the year to see a wide variety of wildlife. The fall migration brings many types of birds to the refuge. Some birds like the mallard, bald eagle, Canada and snow geese winter on the refuge, while others like warblers and shorebirds pass through the refuge on their way to wintering areas further south. During the winter months, large concentrations of ducks and geese can be seen feeding in refuge fields and resting on water areas. Bald eagles may be seen throughout the refuge but most commonly perch in large trees along the Arkansas River or the old river channel.
Marsh hawks are a common sight flying low over refuge fields.
When the seasons change most ducks and other wintering birds return north to their nesting ground. In early summer, white-tailed deer fawns and turkey poults may be seen along wooded roadsides or in forest openings. Herons and egrets feed in shallow water areas and scissor-tailed flycatchers can be seen throughout the refuge. Can Do Holla Bend Refuge is open to the public year-round during daylight hours. A variety of outdoor activities are permitted, but always when the activity is not in conflict with the basic refuge responsibility to wildlife.
