A set of brushes made up of various flying birds. Seagulls, geese, crows, swallows, and all kinds of miscellaneous birds are included. There are 9 brushes of several birds together in a small flock/group, and 13 singular birds. All are silhouettes, so don't expect much detail beyond that. These are great for use in backgrounds!
