Mission
PatchBird Surveys aims to transform structured bird observations into an early-warning system for ecological change, empowering participants to generate consistent data that can guide 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 places relative abundance at the heart of its monitoring approach. Relative abundance refers to the number of individuals detected during a standardised survey at a fixed location and within a defined timeframe. Because survey method and duration are held constant, relative abundance allows comparisons across time and space even when absolute population counts are impractical.
While relative abundance does not provide an exact measure of total population size, it is a valuable indicator of trends, distribution shifts and changes in community composition – particularly across broad geographic areas where intensive census methods are not feasible. Detection rates may vary with habitat structure, weather conditions, species behaviour and observer experience. Standardised protocols reduce these sources of variation, while analytical methods can further account for them as the dataset grows.
What Can the Data Tell Us?
Identifying Priority Areas
Mapping relative abundance patterns at fine spatial and temporal scales allows conservationists to identify habitats of particular importance for breeding, migration, and overwintering. By comparing repeated, standardised surveys across locations, areas that consistently support higher concentrations of birds—or show disproportionate seasonal use—can be distinguished from the surrounding landscape. These insights support strategic decisions about habitat protection, restoration, and long-term stewardship.
Detecting Population Trends
When gathered consistently over time, relative abundance data can indicate whether species are increasing, decreasing, or stable within surveyed locations. Repeated surveys form the basis for detecting temporal patterns, providing early indications of potential population change that can prompt further investigation or conservation action.
Understanding Seasonal Dynamics
Seasonal fluctuations in relative abundance illuminate migration timing, habitat use, and species turnover. These patterns contribute to understanding annual life-cycle phases and can inform targeted conservation actions during sensitive periods such as migration or breeding.
Assessing Conservation Effectiveness
Changes in relative abundance following management or restoration activities offer a quantitative way to examine whether interventions are associated with bird responses, helping assess their effectiveness and inform future management decisions.
Data Quality and Validation
PatchBird Surveys prioritises data quality through standardised methods and integration with established review systems. Standardising survey duration and location reduces variation due to effort, while eBird’s validation filters and community review help flag unusual records for further scrutiny.
As datasets grow, additional quality-control and verification procedures may be applied to strengthen reliability, including expert review of outliers, cross-validation with other monitoring datasets, and analytical checks for consistency.
Data Analysis and Outputs
PatchBird data are analysed to explore spatial and temporal patterns in relative abundance. Analyses may include descriptive summaries, trend indicators, and spatial visualisations that help interpret ecological patterns. Outputs are designed to be scientifically useful while remaining accessible to participants and partners.
More advanced analyses—such as statistical models that address detection variability or integrate PatchBird data with other monitoring sources—are part of ongoing methodological development as the dataset grows.

Objectives
PatchBird Surveys aims to build a standardised, long-term bird monitoring network that can contribute meaningful data to our understanding of changes in bird populations, distribution and community composition. The objectives below define the core framework of the programme and its potential contribution to research and conservation.
Standardised Monitoring Framework
Establish and maintain a consistent survey protocol across a growing network of fixed locations. By using the same survey duration, spatial framework and recording principles, PatchBird Surveys enables observations to be compared across locations, seasons and years while reducing variation caused by differences in survey effort.
Comprehensive Data Integration and Accessibility
Bring standardised survey records together within a consistent analytical framework while retaining eBird as the primary platform for checklist submission and data storage. As the dataset grows, PatchBird Surveys aims to make its structured data increasingly useful for analysis, research and conservation, while ensuring that its methods and outputs remain transparent and accessible.
Long-term Ecological Change and Conservation
Build a long-term dataset capable of revealing changes in bird populations, distribution and community composition over time. By documenting these changes across a growing network of standardised survey sites, PatchBird Surveys aims to provide evidence that can contribute to ecological research, conservation planning and the identification of areas or species requiring further attention.
Why Participate?
Bird populations are changing rapidly, and structured, repeatable observations contribute to early insight into these changes. Each checklist adds value by strengthening spatial and temporal coverage, revealing patterns that isolated records cannot show.
Participation sharpens birding skills, deepens understanding of avian ecology, and connects observers with a global community of contributors. PatchBird also encourages exploration of under-recorded areas, enriching both scientific coverage and personal experience.
Your Role in Science and Conservation
By documenting birds in your area using a consistent method, you provide data that help scientists detect change, identify emerging ecological threats, and guide effective conservation strategies. Your participation creates tangible impact both locally and at larger scales.
Get Involved/How to Get Started
Choose Your Survey Location
Tell us the general area where you plan to conduct your surveys—your neighbourhood, favourite birding site, or a nearby natural area. We will share the corresponding UTM grid reference and instructions for choosing accessible, repeatable survey points.
Join eBird
If you haven’t already, create a free eBird account. eBird provides the tools needed to record and submit your observations to the global database.
Conduct Standardised Surveys
Visit your assigned grid location and conduct a 15-minute stationary count, recording all species seen or heard during the period. Submit your checklist through eBird and share it with the PatchBird Surveys account.
Contribute and Collaborate
Continue surveying your selected locations regularly to strengthen long-term coverage. Encourage others to join and expand the network into new areas, increasing the value of our collective observations.
Data Management & Purpose
All observations collected through PatchBird Surveys are submitted directly to eBird, ensuring 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 visualisations and feedback that keep contributors informed and aware of the value of their observations
-
Identify under-surveyed areas and 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 and contribute to evidence-based conservation planning.
The PatchBird Initiator
PatchBird Surveys was initiated by Gyorgy Szimuly, a Hungarian ornithologist with longstanding involvement in bird monitoring and citizen-science coordination. His work includes contributions to population studies and survey coordination since the early 1990s.
In 2014, he founded World Shorebirds Day and the Global Shorebird Counts, which united volunteers worldwide to document shorebird populations across seasons. These efforts reflect a long-term commitment to bird monitoring, collaboration, and open participation.
As programme coordinator, his role is to maintain a clear, standardised framework that enables birders to contribute meaningful data through existing platforms, particularly eBird, with an emphasis on collective effort, data quality, and long-term conservation value.
