# Dataset Card for Birdsnap Dataset v 1.1.

Welcome to the Birdsnap dataset, consisting of 49,829 images of 500 species of North American birds, collected from Flickr, and corresponding species, bounding box, and part labels.


The dataset distribution also consists of the following files:

1. species.txt
This file lists the species in the dataset.  The first line is a header.  Each subsequent line represents a species.  Lines are tab-delimited, and the fields
are:
- id: An integer id for the species.  These ids run from 1 to 500 for the 500   species.
- common: The common English name of the species, for example "Blue Jay."
- scientific: The scientific (Latin) name of the species, for example   "Cyanocitta cristata."
- dir: The name of the a directory in which to store the images of this   species.  This is just the common name with spaces and other   dangerous-in-file-path characters replaced or removed.

2. images.txt
This file lists the images in the dataset, with the coresponding bounding boxes, part locations, and species labels.  Like species.txt, it is tab-delimited with the first line giving field names.  The fields are:
- url: The URL from which the image was downloaded.
- md5: An MD5 sum of the image file constants.
- path: The local path of the image.
- species_id: The id of the species of the labeled bird in the image.
- bb_x1, bb_y1, bb_x2, bb_y2: The coordinates of the top-left (bb_x1, bb_y1)   and bottom-right (bb_x2, bb_y2) corners of the bounding box of the labeled
  bird.
- ${part}_x, ${part}_y: The coordinates of part ${part}.  Parts are back, beak,   belly, breast, crown, forehead, left_cheek, left_eye, left_leg, left_wing,   nape, right_cheek, right_eye, right_leg, right_wing, tail, throat.

3. test_images.txt
This file lists the 2443 test images used in the species identification experiments in the paper.  It has a header line, then the "path" (from images.txt) of each test image, one per line.
