For pre-training, we provide a new large-scale dataset [WildlifeReID-10k](https://www.kaggle.com/datasets/wildlifedatasets/wildlifereid-10k) with 10k identities and around 140k images. \nFor testing, we have curated a dataset consisting of never-seen data of three species: (i)🐢 loggerhead sea turtles (Zakynthos, Greece), (ii) 🦎 salamanders (Czech Republic), and (iii) 🐆 Eurasian lynxes (Czech Republic). \n\n**The test dataset is split into two main subsets:**\n- **📂 Database** – Contains labeled data about the individuals.\n- **🔍 Query** – Consists of images for identification, where the task is to determine whether the individual is known (present in the database) or new (not present in the database).\n\n## File Structure\n\nThe dataset is organized into structured directories to allow easy access and processing. It consists of labeled images for known individuals (*Database*) and unlabeled images (*Query*) requiring identification, metadata, and a sample submission file. \n\n- **📂 `images/{SeaTurtleID2022, SalamanderID2025, LynxID2025}/database/`** – Contains labeled images of known individuals, serving as the reference set. \n- **🔍 `images/{SeaTurtleID2022, SalamanderID2025, LynxID2025}/query/`** – Contains images to be identified.\n- **📄 `metadata.csv`** – Provides dataset metadata, including database-query splits and individual identities. \n- **📑 `sample_submission.csv`** – A sample submission file illustrating the required format for predictions. \n\n## Data loading and description\n\nPlease check the provided [notebook](https://www.kaggle.com/code/wildlifedatasets/animalclef2025). The simplest way of loading the dataset is via the [wildlife-datasets](https://github.com/WildlifeDatasets/wildlife-datasets) package via\n\n```\nfrom wildlife_datasets.datasets import AnimalCLEF2025\n\ndataset = AnimalCLEF2025(root)\n```\n\nThis is the dataset with metadata\n\n```\ndatasets.metadata\n```\n\ncontaining the following columns:\n\n* `image_id` - id of the image. Only for internal purposes.\n* `path` - path of the image.\n* `date` - date when the image was taken (can be missing).\n* `orientation` - orientation of the relevant body part (can be missing).\n* `species` - which species the photo depicts.\n* `dataset` - which of the 3 datasets the image belongs to.\n\n## Sample submission\n\nThe above-mentioned notebook provides the function `create_sample_submission`, which creates the sample submission. For each query image (in rows), it needs to be predicted whether the individual is in the database (and then to predict its identity) or not (and then predict it as new_individual).", "isPublished": false, "hasIsPublished": false, "postTitle": "", "hasPostTitle": false, "mimeType": "", "hasMimeType": false }, { "name": "Competition Description", "content": "\n## Motivation\n\nAnimal re-identification is crucial for studying various aspects of wildlife, including tracking populations, monitoring movements, examining behaviors, and managing species. Despite variations in how animal re-identification is defined and approached across studies, its objective remains consistent. The primary aim is to accurately and efficiently identify individual animals within a species by recognizing unique traits, such as markings, patterns, or other distinctive features. Automating this process allows for collecting detailed, large-scale data on population dynamics, migration routes, habitat use, and behaviors. This data empowers researchers to track movements, assess population sizes, and observe demographic changes, providing invaluable insights into species dynamics. Such information is essential for identifying biodiversity threats and crafting evidence-based conservation strategies. Despite great progress in machine learning, many models for animal re-identification still struggle with overfitting. They often focus too much on background details - like lighting or landscape - rather than the animal's unique features. As a result, these models perform well in familiar environments but fail in new or varied conditions. This limitation makes it harder to accurately identify animals in diverse habitats, reducing the models' usefulness in real-world conservation efforts. Improving their ability to generalize is essential for more reliable animal identification.\n\n## What will you learn?\n\nYou will learn about the exciting field of animal re-identification and learn to recognize individual wild animals. You will learn how to create images such as the one below. It shows a test image of an unknown loggerhead sea turtle (left) and an image from the training set of a known sea turtle Nerea (or t266 in scientific notation). It also shows the automatically extracted keypoints and their matches between both images. Visual analysis of both the matches and the post-occular scutes reveals that both turtles are indeed the same. Therefore, we managed to identify the unknown turtle as Nerea.\n\n![](https://www.googleapis.com/download/storage/v1/b/kaggle-user-content/o/inbox%2F12294787%2F235ea09aaf82b9ec51a65a5c8a338c47%2FMatches.png?generation=1737379938870017&alt=media)", "isPublished": false, "hasIsPublished": false, "postTitle": "", "hasPostTitle": false, "mimeType": "", "hasMimeType": false }, { "name": "rules", "content": "##ENTRY IN THIS COMPETITION CONSTITUTES YOUR ACCEPTANCE OF THESE OFFICIAL COMPETITION RULES.\n\n**[See Section 3.18 for defined terms](rules#18.-terms)**\n\n*The Competition named below is a skills-based competition to promote and further the field of data science.

TEAM LIMITS\na. The maximum Team size is five (10).\nb. Team mergers are allowed and can be performed by the Team leader. In order to merge, the combined Team must have a total Submission count less than or equal to the maximum allowed as of the Team Merger Deadline. The maximum allowed is the number of Submissions per day multiplied by the number of days the competition has been running.\n\n####2. SUBMISSION LIMITS\na. You may submit a maximum of five (5) Submissions per day.\nb. You may select up to two (2) Final Submissions for judging.\n\n####3. COMPETITION TIMELINE\na. Competition Timeline dates (including Entry Deadline, Final Submission Deadline, Start Date, and Team Merger Deadline, as applicable) are reflected on the competition’s Overview > Timeline page.\n\n####4. COMPETITION DATA\n\na. Data Access and Use.\n\n1. Competition Use and Non-Commercial & Academic Research: You may access and use the Competition Data for non-commercial purposes only, including for participating in the Competition and on Kaggle.com forums, and for academic research and education. The Competition Sponsor reserves the right to disqualify any Participant who uses the Competition Data other than as permitted by the Competition Website and these Rules.\n\n2. The user of this dataset must follow the provided license of SeaTurtleID2022 and acknowledge the accompanying paper. In particular, it prohibits commercial applications and being re-uploaded. If WildlifeReID-10k was used as a training database, its license file must be followed.\n\nb. Data Security. \n\n1. You agree to use reasonable and suitable measures to prevent persons who have not formally agreed to these Rules from gaining access to the Competition Data. You agree not to transmit, duplicate, publish, redistribute or otherwise provide or make available the Competition Data to any party not participating in the Competition. You agree to notify Kaggle immediately upon learning of any possible unauthorized transmission of or unauthorized access to the Competition Data and agree to work with Kaggle to rectify any unauthorized transmission or access.\n\n####5. WINNER LICENSE \n\na. Under Section 2.8 (Winners Obligations) of the General Rules below, you hereby grant and will grant the Competition Sponsor the following license(s) with respect to your Submission if you are a Competition winner:\n\n1. Open Source: You hereby license and will license your winning Submission and the source code used to generate the Submission under an Open Source Initiative-approved license (see [www.opensource.org] (http://www.opensource.org)) that in no event limits commercial use of such code or model containing or depending on such code. \n\n2. For generally commercially available software that you used to generate your Submission that is not owned by you, but that can be procured by the Competition Sponsor without undue expense, you do not need to grant the license in the preceding Section for that software. \n\n3. In the event that input data or pretrained models with an incompatible license are used to generate your winning solution, you do not need to grant an open source license in the preceding Section for that data and/or model(s). \n\nb. You may be required by the Sponsor to provide a detailed description of how the winning Submission was generated, to the Competition Sponsor’s specifications, as outlined in Section 2.8, Winner’s Obligations. This may include a detailed description of methodology, where one must be able to reproduce the approach by reading the description, and includes a detailed explanation of the architecture, preprocessing, loss function, training details, hyper-parameters, etc. The description should also include a link to a code repository with complete and detailed instructions so that the results obtained can be reproduced.\n \n####6. EXTERNAL DATA AND TOOLS\n\na. You may use data other than the Competition Data (“External Data”) to develop and test your Submissions. However, you will ensure the External Data is either publicly available and equally accessible to use by all Participants of the Competition for purposes of the competition at no cost to the other Participants, or satisfies the Reasonableness criteria as outlined in Section 2.6.b below. The ability to use External Data under this Section does not limit your other obligations under these Competition Rules, including but not limited to Section 2.8 (Winners Obligations). \n\nb. The use of external data and models is acceptable unless specifically prohibited by the Host. Because of the potential costs or restrictions (e.g., “geo restrictions”) associated with obtaining rights to use external data or certain software and associated tools, their use must be “reasonably accessible to all” and of “minimal cost”. Also, regardless of the cost challenges as they might affect all Participants during the course of the competition, the costs of potentially procuring a license for software used to generate a Submission, must also be considered. The Host will employ an assessment of whether or not the following criteria can exclude the use of the particular LLM, data set(s), or tool(s):\n\n1. Are Participants being excluded from a competition because of the \"excessive\" costs for access to certain LLMs, external data, or tools that might be used by other Participants. The Host will assess the excessive cost concern by applying a “Reasonableness” standard (the “Reasonableness Standard”). The Reasonableness Standard will be determined and applied by the Host in light of things like cost thresholds and accessibility.\n\n2. By way of example only, a small subscription charge to use additional elements of a large language model such as Gemini Advanced are acceptable if meeting the Reasonableness Standard of Sec. 8.2. Purchasing a license to use a proprietary dataset that exceeds the cost of a prize in the competition would not be considered reasonable.\n\nc. Automated Machine Learning Tools (“AMLT”)\n\n1. Individual Participants and Teams may use automated machine learning tool(s) (“AMLT”) (e.g., Google toML, H2O Driverless AI, etc.) to create a Submission, provided that the Participant or Team ensures that they have an appropriate license to the AMLT such that they are able to comply with the Competition Rules. \n\n####7. ELIGIBILITY\n\na. Unless otherwise stated in the Competition-Specific Rules above or prohibited by internal policies of the Competition Entities, employees, interns, contractors, officers and directors of Competition Entities may enter and participate in the Competition, but are not eligible to win any Prizes. \"Competition Entities\" means the Competition Sponsor, Kaggle Inc., and their respective parent companies, subsidiaries and affiliates. If you are such a Participant from a Competition Entity, you are subject to all applicable internal policies of your employer with respect to your participation.\n\n####8. WINNER’S OBLIGATIONS\n\na. As a condition to being awarded a Prize, a Prize winner must fulfill the following obligations:\n\n1. Deliver to the Competition Sponsor the final model's software code as used to generate the winning Submission and associated documentation. The delivered software code should follow [these documentation guidelines][5], must be capable of generating the winning Submission, and contain a description of resources required to build and/or run the executable code successfully. For avoidance of doubt, delivered software code should include training code, inference code, and a description of the required computational environment. \n\na. To the extent that the final model’s software code includes generally commercially available software that is not owned by you, but that can be procured by the Competition Sponsor without undue expense, then instead of delivering the code for that software to the Competition Sponsor, you must identify that software, method for procuring it, and any parameters or other information necessary to replicate the winning Submission; Individual Participants and Teams who create a Submission using an AMLT may win a Prize. However, for clarity, the potential winner’s Submission must still meet the requirements of these Rules, including but not limited to Section 2.5 (Winners License), Section 2.8 (Winners Obligations), and Section 3.14 (Warranty, Indemnity, and Release).” \n\nb. Individual Participants and Teams who create a Submission using an AMLT may win a Prize. However, for clarity, the potential winner’s Submission must still meet the requirements of these Rules,\n\n2. Grant to the Competition Sponsor the license to the winning Submission stated in the Competition Specific Rules above, and represent that you have the unrestricted right to grant that license;\n\n3. Sign and return all Prize acceptance documents as may be required by Competition Sponsor or Kaggle, including without limitation: (a) eligibility certifications; (b) licenses, releases and other agreements required under the Rules; and (c) U.S. tax forms (such as IRS Form W-9 if U.S. resident, IRS Form W-8BEN if foreign resident, or future equivalents).\n\n####9. GOVERNING LAW\n\na. Unless otherwise provided in the Competition Specific Rules above, all claims arising out of or relating to these Rules will be governed by California law, excluding its conflict of laws rules, and will be litigated exclusively in the Federal or State courts of Santa Clara County, California, USA.

DEFINITIONS\na. \"Competition Data\" are the data or datasets available from the Competition Website for the purpose of use in the Competition, including any prototype or executable code provided on the Competition Website. The Competition Data will contain private and public test sets. Which data belongs to which set will not be made available to Participants. \nb. An “Entry” is when a Participant has joined, signed up, or accepted the rules of a competition. Entry is required to make a Submission to a competition.\nc. A “Final Submission” is the Submission selected by the user, or automatically selected by Kaggle in the event not selected by the user, that is/are used for final placement on the competition leaderboard.\nd. A “Participant” or “Participant User” is an individual who participates in a competition by entering the competition and making a Submission.\ne. The “Private Leaderboard” is a ranked display of Participants’ Submission scores against the private test set. The Private Leaderboard determines the final standing in the competition.\nf. The “Public Leaderboard” is a ranked display of Participants’ Submission scores against a representative sample of the test data. This leaderboard is visible throughout the competition.\ng. A “Sponsor” is responsible for hosting the competition, which includes but is not limited to providing the data for the competition, determining winners, and enforcing competition rules.\nh. A “Submission” is anything provided by the Participant to the Sponsor to be evaluated for competition purposes and determine leaderboard position. A Submission may be made as a model, notebook, prediction file, or other format as determined by the Sponsor.\ni. A “Team” is one or more Participants participating together in a Kaggle competition, by officially merging together as a Team within the competition platform.\n\n [1]: https://www.treasury.gov/resource-center/sanctions/Programs/Pages/Programs.aspx\n [2]: http://www.kaggle.com/terms\n [3]: http://www.opensource.org\n [4]: http://www.opensource.org\n [5]: https://www.kaggle.com/WinningModelDocumentationGuidelines\n [6]: http://www.kaggle.com/privacy\n [7]: http://www.kaggle.com/contact\n", "isPublished": false, "hasIsPublished": false, "postTitle": "", "hasPostTitle": false, "mimeType": "", "hasMimeType": false }, { "name": "Other Resources", "content": "**Besides this Kaggle page, make sure to check these other resources:**\n\n**Relevant tools and papers**:\n- [WildlifeReID-10k Dataset Paper](https://arxiv.org/abs/2406.09211)\n- [WildlifeDatasets](https://github.com/WildlifeDatasets/wildlife-datasets)\n- [WildlifeTools](https://github.com/WildlifeDatasets/wildlife-tools)\n- [MegaDescriptor](https://openaccess.thecvf.com/content/WACV2024/papers/Cermak_WildlifeDatasets_An_Open-Source_Toolkit_for_Animal_Re-Identification_WACV_2024_paper.pdf)\n- [WildFusion](https://arxiv.org/pdf/2408.12934)\n\n**Other competitions and workshops related info:**\n- [LifeCLEF 2025 website](https://www.imageclef.org/LifeCLEF2025) for more information about LifeCLEF challenges and working notes submission procedure.\n- [FGVC12 website](https://sites.google.com/view/fgvc12) for more information about the FGVC12 workshop.", "isPublished": false, "hasIsPublished": false, "postTitle": "", "hasPostTitle": false, "mimeType": "", "hasMimeType": false }, { "name": "Evaluation", "content": "## Submission File\n\nThe submission file contains only two columns. The first column is image_id (corresponds to the metadata of all query images) and is always fixed, as shown in the sample_submission file. The second column is either the `new_individual` or prediction of the new individual (always in the form `LynxID2025_???`, `SalamanderID2025_???`, `SeaTurtleID2022_???`). This [notebook](https://www.kaggle.com/code/wildlifedatasets/animalclef2025) notebook provides the function `create_sample_submission`, which creates the sample submission from predictions.\n\n## Evaluation metrics\n\nThere are two metrics computed:\n\n* BAKS (balanced accuracy on known samples) - computes the accuracy for individuals which are known (in the database). It is balanced over classes (individuals).\n* BAUS (balanced accuracy on unknown samples) - computes the accuracy for individuals which are unknown (not in the database). It is balanced over classes (individuals).\n\nThe final accuracy is the *geometric* mean of the two accuracies. We decided to use the geometric mean `np.sqrt(x*y)` instead of the arithmetic mean `0.5*(x+y)` because the submission predicting all images as new individuals achieves 0% BAKS but 100% BAUS and its arithmetic mean would be 50% even though the model is useless.
