Data sheets used to record species observed on point counts.

Point counts on Arcadia Plantation and Tall Timbers are conducted in May and June of each year. Three visits are made to each station each year, and adult birds observed within 250 m of the count circle are tallied. Counts are aggregated using three distance limits of 50, 100, and 100-250 m.

In 2011, 61 different species were recorded on point counts on Tall Timbers while 45 different species were observed on counts on Arcadia. These differences are attributable to the extensive areas of freshwater marsh and hardwood hammock present on Tall Timbers (e.g., Lake Iamonia and Woodyard Hammock).

Eastern Towhee was the most common bird in upland pine forests on Tall Timbers, while Bachman’s Sparrow was most common on Arcadia. Northern Bobwhite placed third on both sets of counts, while Northern Cardinals ranked second on Tall Timbers and ninth on Arcadia.
