+
+### Dataset Summary
+
+The Caltech-UCSD Birds 200-2011 dataset (CUB-200-2011) is an extended version of the original CUB-200 dataset, featuring photos of 200 bird species primarily from North America. This 2011 version significantly expands its predecessor by doubling the number of images per class and introducing new part location annotations, alongside collecting detailed natural language descriptions for each image through Amazon Mechanical Turk (AMT). The dataset includes a total of 11,788 images, split into 5,994 for training and 5,794 for testing.
+
+### Supported Tasks and Leaderboards
+
+This dataset can support a variety of computer vision tasks, including but not limited to:
+
+* Fine-Grained Image Classification
+* Object Detection and Localization
+* Semantic Segmentation
+* Attribute-Based Recognition
+* Multitask Learning
+
+### Languages
+
+The dataset includes annotations in English
+
+## Dataset Structure
+
+### Data Instances
+
+A data instance in the CUB-200-2011 dataset comprises an image of a bird species, along with annotations including bounding boxes, part locations, binary attributes, and natural language descriptions.
+
+
+### Data Fields
+
+* images: Photographs of birds across 200 species.
+* annotations: This includes:
+  * bounding boxes: Specify the bird's location within the image.
+  * segmentation labels: Provide pixel-wise segmentation for precise object segmentation.
+  * part locations: 15 specific parts of the bird are annotated for detailed analysis.
+  * binary attributes: 312 attributes indicating the presence or absence of certain features or behaviors.
+  * natural language descriptions: Ten single-sentence descriptions per image, collected via AMT.
+
+
+### Data Splits
+
+* Training set: 5,994 images
+* Test set: 5,794 images
+
+## Considerations for Using the Data
+
+### Social Impact of Dataset
