This dataset contains the Caltech-UCSD Birds-200-2011 (CUB-200-2011) dataset, from here.
Each example consists of an image, a label, and a bounding box. (The dataset also contains x/y locations of "parts", e.g. beak, right eye, left wing, throat, etc. and "attributes", e.g. beak shape, wing color, feather pattern. I have not included either of these. Contact me if you want me to add them.)
Note: Some of these images are also in ImageNet!… See the full description on the dataset page:
