Species of the Year: Hirondelles and Martinets
Swallows and Martinets Take Center Stage as 2025 Species of the year

Following a year dedicated to the Athena’s Owl in 2024, attention turns skyward in 2025 as swallows and martinets are celebrated as the Species of the Year. These aerial birds,often seen as symbols of spring,are integral to our environment,nesting under eaves and within building crevices,gracefully traversing rural and urban landscapes in their pursuit of insects.
Despite their familiarity, swallow and martinet populations are facing a concerning decline. Habitat destruction, dwindling food sources, and changes in building construction pose meaningful threats to these beloved birds.
Addressing the Challenges: Key Objectives for Conservation
To combat these challenges, two primary objectives have been established:
- Monitoring window Swallow Populations: Implement complete tracking within designated “sentinel Municipalities.” This involves conducting thorough annual surveys within selected towns to monitor population changes.
- Data Collection Across Species: Gather extensive data on window swallows, rock swallows, black swifts, and white-bellied martinets. Increased data on occupied sites will facilitate the implementation of effective conservation strategies.
How to Get Involved in Swallow and Martinet Conservation
Several avenues exist for those interested in participating in the conservation effort:
- Become a reference for a Sentry Commune registration.
- Report opportunistic observations.
- Survey a commune where data is lacking; a municipal list is available.
- Participate in organized field programs.
Reporting Your Observations
Share your findings through the following platforms:
Focus on reproductive data, such as individuals observed in nests or entering cavities.
Data Collection Guidelines
To ensure data accuracy and usefulness, adhere to the following guidelines:
- Provide well-localized data with accurate GPS coordinates, ideally at the building scale.
- Submit one data point per building per species (e.g., six swallow nests, one cavity visited by a swift).
- Include a reproduction code (9, 13, 16, etc.).
- Ideally, include a photo (discreetly taken) and a comment.
- Utilize the colony module for detailed nest details.
A tutorial is available to guide data entry on Naturalist.
Volunteer Mobilization: The Key to Success
As with the Athena’s Owl initiative, the 2025 Species of the Year program relies heavily on volunteer participation. Your involvement is crucial for enhancing our understanding and improving the protection of these species.
Major Challenges for 2025
Three primary challenges are proposed for the year:
- Monitor Three Sentinel Municipalities per Local Group: Each sector aims to establish monitoring in at least three municipalities already committed to biodiversity, conducting a complete inventory of window swallow populations.
- Survey Three Municipalities Without swallow Data per Local Group: Currently, a significant number of municipalities lack swallow data. The goal is to survey at least three of these municipalities per local group to address these gaps.
- Double Black Swift Reproduction Data: Building on the previous year’s data, the objective is to double the amount of black swift reproduction data collected. Every observation counts!
By collectively addressing these challenges, we can significantly advance the knowlege and protection of swallows and martinets.
Resources and Contacts
For inquiries, contact Julie Coutout. Additional support will be available from Pauline and Angie (interns from mid-May to the end of July) and Emilie Wacker (civic service).
A prospecting assistance guide is available to assist in locating and identifying suitable habitats.


Throughout the year, opportunities will be provided to learn more about these species, participate in their monitoring, and contribute to their conservation.
Swallows and Martinets: Unveiling the 2025 Species of the Year

Why are Swallows and Martinets the focus of 2025?
Following the 2024 focus on the Athena’s Owl, the spotlight shifts in 2025 too swallows and martinets. These birds, frequently enough seen as harbingers of spring, are vital to our habitat. They gracefully navigate both rural and urban landscapes, nesting in various locations and feeding on insects. Though, their populations are facing threats.
What Threats Do Swallows and Martinets Face?
the primary threats to swallow and martinet populations include:
Habitat destruction
Dwindling food sources
Changes in building construction
These factors contribute to a concerning decline in their numbers.
What are the Main Goals of the 2025 Species of the Year initiative?
The initiative has two main objectives to address these challenges:
- Monitoring Window Swallow Populations: This involves complete tracking within designated “sentinel Municipalities,” conducting thorough annual surveys.
- Data Collection Across Species: Gathering extensive data on window swallows, rock swallows, black swifts, and white-bellied martinets. Increased data collection on where they are found will facilitate effective conservation.
How Can I Get Involved in Swallow and Martinet Conservation?
There are multiple ways to contribute to the conservation effort:
Become a reference for a Sentry Commune registration.
Report any opportunistic observations.
Survey a municipality that lacks data; a municipal list is available.
Participate in organized field programs.
where Can I Report My Swallow and Martinet Sightings?
You can share your findings through these platforms:
Focus your reports on reproductive data, such as observations of individuals in nests or entering cavities.
What Data Collection Guidelines Should I Follow?
To ensure data accuracy and usefulness, follow these guidelines:
Provide well-localized data with precise GPS coordinates, ideally at the building scale.
Submit one data point per building per species. For example, six swallow nests within the same building would be recorded as one data point.
Include a reproduction code (e.g., 9, 13, 16).
Include a photo and a comment (optional).
Utilize the colony module for detailed nest details.
Where Can I Find a Tutorial for Data Entry?
A tutorial is available to assist with data entry on Naturalist.
Why is Volunteer Participation So Notable?
Similar to the Athena’s Owl initiative, the success of the 2025 Species of the Year program heavily relies on volunteer participation. your involvement plays a crucial role in enhancing our understanding and improving the protection of these species.
What are the Key challenges for 2025?
There are three primary challenges for the year:
- Monitor Sentinel Municipalities: Establish monitoring in at least three municipalities per local group that is already committed to biodiversity.Conduct a complete inventory of window swallow populations.
- Survey Municipalities Without Data: Survey at least three municipalities per local group that currently lack swallow data.
- Double Black Swift Data: Double the amount of black swift reproduction data collected. Every observation is valuable.
Are there any specific Swallow and Martinet species of particular conservation concern?
The initiative specifically seeks data on:
window Swallows
Rock Swallows
Black Swifts
White-bellied Martinets
Where can I find additional resources or contact someone with questions?
For inquiries, contact Julie Coutout. Additional support will be available from Pauline and Angie (interns from mid-May to the end of July) and Emilie Wacker (civic service).
A prospecting assistance guide is also available to help with locating and identifying suitable habitats.
Summary of Key Initiatives
| Initiative | Description |
| :———————————————————— | :————————————————————————————————————————————————————- |
| Monitoring Sentinel Municipalities | Conduct complete inventories of window swallow populations in existing biodiversity municipalities. |
| Municipal Surveys | Survey municipalities lacking swallow data, aiming to survey a minimum number per local group. |
