Mission
PatchBird’s mission is to transform structured bird observations into an early-warning system for ecosystem change, empowering people to contribute meaningful data that guides timely, evidence-based conservation. Our vision is a future where bird populations thrive, habitats are protected, and decisions are informed by continuous, locally grounded monitoring at a global scale.
The Role of Relative Abundance
PatchBird Surveys place relative abundance at the heart of its monitoring approach. Relative abundance reflects the estimated number of birds detected within a defined area and timeframe, adjusted for effort-based variables such as time spent surveying, distance covered, and observer skill.
Unlike absolute abundance – which demands intensive, resource-heavy survey methods – relative abundance is highly scalable. This makes it exceptionally well-suited to citizen-science platforms like eBird, where structured observations collected consistently across time and space can reveal clear, robust population patterns.
Identifying Priority Areas
Mapping relative abundance at fine spatial and temporal scales helps conservationists identify habitats of critical importance for breeding, migration, and overwintering. These insights support strategic decisions about habitat protection, restoration, and long-term site stewardship.
Detecting Population Trends
When gathered consistently over time, relative abundance data highlight whether species are declining, increasing, or remaining stable. These trends provide early warning signals and help trigger timely, proactive conservation responses.
Understanding Seasonal Dynamics
Seasonal fluctuations in relative abundance illuminate migration timing, habitat use, and species turnover. This information guides targeted conservation efforts during sensitive periods such as breeding seasons or long-distance migrations.
Assessing Conservation Effectiveness
Changes in relative abundance following conservation interventions – such as habitat management, restoration, or predator control – offer a clear, measurable way to evaluate outcomes and inform adaptive, evidence-based decision-making.

Objectives
Building on the central role of relative abundance as an early indicator of ecological change, PatchBird Surveys aim to translate structured observations into meaningful conservation outcomes. To achieve this, PatchBird is guided by the objectives listed below.
Early Detection and Proactive Conservation
Develop a globally coordinated monitoring system that uses relative abundance trends to identify emerging declines before they become critical, enabling conservation actions to be taken at the most effective moment.
Standardised Monitoring Framework
Apply a grid-based approach using the Universal Transverse Mercator (UTM) system to ensure that relative abundance data are collected consistently across regions, habitats, and seasons – creating a comparable dataset at global scale.
Comprehensive Data Integration and Accessibility
Integrate effort-adjusted eBird observations into robust analytical pipelines that convert raw data into high-resolution abundance maps, trend summaries, and practical insights for conservation practitioners and decision-makers.
Citizen Scientist Engagement and Education
Provide birders with clear, standardised survey protocols to improve the quality of relative abundance data. Strengthening understanding of methodology fosters long-term engagement and increases the precision of citizen-science contributions.
Global Collaboration and Partnerships
Strengthen collaboration among birders, researchers, conservation organisations, and local communities to build a unified global monitoring network. These partnerships ensure that PatchBird data, tools, and insights directly support conservation planning and policy.
Ecosystem-Level Conservation Focus
Use relative abundance patterns to shift attention from single-species concerns toward ecosystem resilience, habitat integrity, and landscape-scale processes – supporting more holistic conservation strategies.
Efficient Resource Allocation
Leverage fine-scale abundance trends to inform where conservation resources can have the greatest impact, ensuring interventions are timely, targeted, and cost-effective.
Ethical Data Collection and Transparency
Promote responsible, ethical bird monitoring practices and maintain open access to data summaries and results, fostering collaboration and trust among researchers, conservationists, and communities.
Why participate?
Bird populations are changing faster than ever, often in ways that remain invisible until declines become severe. By contributing structured, repeatable observations, you help reveal these changes early — when conservation action is still possible. PatchBird turns individual effort into collective insight, ensuring that every checklist adds value beyond a single moment in the field.
Empower Conservation
Every bird you record contributes to a growing body of evidence on species distribution, behaviour, and population trends. These data help identify emerging risks, guide conservation priorities, and support decisions grounded in real-world observations.
Learn and Improve
Participation sharpens your birding skills, deepens your understanding of avian ecology, and connects you with a global community of observers. PatchBird also encourages exploration of under-recorded areas, enriching both personal experience and scientific coverage.
Act Locally, Impact Globally
Your observations build a detailed picture of birdlife in your own patch while contributing to a coordinated global monitoring effort. This dual perspective strengthens local conservation initiatives and informs broader, international research.
Be Part of Something Bigger
PatchBird is more than a data collection effort — it is a shared commitment to understanding and protecting the natural world. By taking part, you join a growing network of people helping to safeguard birds and ecosystems for future generations.
Your Role in Science and Conservation
Bird populations are under pressure from habitat loss, climate change, and a range of human-driven impacts. By documenting the birds in your area, you provide essential data that helps scientists detect change, identify emerging threats, and guide effective conservation strategies. Your participation creates real, lasting impact.
Get involved
PatchBird Surveys offer a meaningful way to contribute to global ornithology by combining structured citizen science with modern technology. Built on the foundation of the eBird platform, PatchBird empowers birders and nature enthusiasts to document their observations using a standardised method anchored in the UTM grid system. Each checklist becomes part of a powerful, spatially organised dataset used by researchers, conservationists, and policymakers worldwide.
Whether you're an experienced birder or a curious beginner, your participation genuinely matters. Every observation strengthens our understanding of how bird populations are changing at both local and global scales.
How to get started
Choose Your Survey Spot(s)
Tell us the general area where you plan to conduct your surveys – your neighbourhood, a favourite birding site, or a place near your workplace. We will generate and share the UTM grid reference for your chosen area.
Join eBird
If you haven’t already, create a free eBird account via the website or mobile app. eBird is simple to use and provides all the tools needed to record your observations.
Start Observing
Visit your assigned UTM grid corner and conduct a 15-minute stationary survey following the PatchBird methodology. Record species, time, effort, and details directly in the eBird app.
Contribute to PatchBird Surveys
Explore under-reported areas within your grid or beyond. Observations from these lesser-surveyed places are especially valuable, filling gaps in our global understanding of bird distribution and seasonal movement.
Share Your Checklist
Before submitting, add the project’s eBird username (eBirdUTM) to your sharing contacts and share your checklist with us. This ensures your data is included in the PatchBird database.
Encourage Others
Invite friends, family, and fellow birders to join. Your enthusiasm helps expand the network and amplify the impact of our collective monitoring efforts.
Data management & purpose
All observations collected through PatchBird Surveys are submitted directly to eBird, ensuring that data are securely stored, globally accessible, and integrated into one of the world’s leading biodiversity databases.
PatchBird does not operate as a standalone data repository. Instead, the initiative focuses on analysing submitted checklists to understand spatial coverage, survey effort, participant activity, species trends, and seasonal patterns. These analyses serve several key purposes:
-
Provide timely feedback and visualisations that keep contributors informed, engaged, and aware of the value of their observations;
-
Identify under-surveyed areas and help guide future survey priorities;
-
Highlight emerging patterns that may warrant further scientific investigation or targeted monitoring.
Looking ahead, PatchBird seeks to strengthen collaboration with academic institutions and conservation organisations to increase the scientific utility of these data. Such partnerships will support early detection of population change and contribute to evidence-based conservation planning at multiple scales.
By promoting structured, effort-adjusted observations within a consistent UTM grid framework, PatchBird maximises the quality and long-term value of every checklist – whether used in large-scale analyses or as a clear reminder to each participant that their observations matter.
The PatchBird Initiator
PatchBird Surveys was initiated by Gyorgy Szimuly, a Hungarian ornithologist with long-standing involvement in bird monitoring and citizen-science coordination. His work in avian surveys dates back to the early 1990s, including contributions through the Bird Monitoring Centre of BirdLife Hungary, where he was involved in population studies and survey coordination.
In 2014, he founded World Shorebirds Day and the Global Shorebird Counts that brought together volunteers worldwide to document shorebird populations across breeding, migration, and non-breeding areas. These projects reflect a long-term commitment to bird monitoring, collaboration, and open participation.
As the program coordinator of PatchBird, his role is to develop and maintain a clear, standardised framework that enables birders to contribute meaningful data through existing platforms, primarily eBird. The emphasis of the initiative remains on collective effort, data quality, and long-term conservation value rather than individual ownership.
