A Shift in Focus: From Owls to aerial Acrobats

Following a year dedicated to the discreet and endearing Little Owl (Athene noctua) in 2024,conservation efforts are now turning skyward.For 2025, the spotlight shines on swallows and martins, iconic birds deeply intertwined wiht our daily lives.

The Plight of Aerial Insectivores: Declining Populations

These aerial insectivores, often seen nesting under eaves and darting across our landscapes in pursuit of insects, are facing significant population declines. Despite their familiarity, swallow and martin populations are threatened by habitat destruction, dwindling food sources, and changes in building construction. Recent studies indicate a concerning trend, with some European populations experiencing declines of up to 40% in the last two decades.

Conservation goals: Monitoring and Data Collection

To address these challenges, two primary objectives have been established:

1. Tracking Population Trends: Implementing comprehensive monitoring programs in sentinel municipalities to meticulously track the population dynamics of the House Martin (Delichon urbicum). This involves conducting thorough surveys within selected towns and repeating them annually to observe population changes.
2. Gathering Comprehensive Data: Collecting extensive data on various species, including the House Martin, Crag Martin (Ptyonoprogne rupestris), Common Swift (Apus apus), and Pallid Swift (Apus pallidus).The more facts available about occupied sites, the more effective conservation strategies can be developed and implemented.

get Involved: Citizen Science Opportunities

You can contribute to the conservation of these vital species in several ways:

• Become a Sentinel Municipality Referent: Register to lead monitoring efforts in a designated sentinel municipality.
• Report Opportunistic Observations: Share any sightings of swallows and martins you encounter.
• Survey Undocumented Areas: Explore municipalities were data is lacking and document any presence of these birds.
• Participate in Organized Field Surveys: Join scheduled survey programs to contribute to data collection efforts.

Data Submission: Precision is Key

Share your observations thru online platforms such as Naturalist or www.faune-aura.org. Reproductive data, such as observations of individuals in nests or entering cavities, are especially valuable.

To ensure data accuracy, please provide:

• Well-Localized Data: Precise GPS coordinates, ideally accurate to the building level.
• Detailed Observations: Comprehensive information about the observed behavior and habitat.

The 2025 Species of the Year: A Call to Action for Swallow and Swift conservation

The focus for this year is on gathering crucial data about swallow and black swift populations. This initiative relies heavily on the dedication of volunteers to enhance our understanding and bolster the protection of these vital bird species.Your participation is key to making a real difference.

Citizen science initiatives are increasingly vital for ecological research. For example, the Christmas bird Count, run by the Audubon Society, has been collecting bird data for over a century, providing invaluable insights into population trends.

Key Objectives for Swallow and Swift Monitoring

This year’s project presents three significant challenges designed to expand our knowledge of swallow and black swift populations:

How to Contribute: Data Collection Guidelines

To ensure data accuracy and consistency, volunteers are asked to record the following information for each observation:

• Data on buildings and Species: Record details such as the number of swallow nests or swift cavities observed. For example: 6 swallow nests; 1 cavity visited by a swift.
• Reproduction Code: Use the designated reproduction codes to indicate the breeding status of the birds (e.g., 9, 13, 16).
• Visual Documentation: Whenever possible, include a photograph of the observation (can be hidden for privacy).
• Comments: Add any relevant comments or notes about the observation.
• Colony Module: Utilize the colony module for detailed information about nest locations and characteristics.

Data can be entered via naturalist platforms, ensuring accessibility and collaborative analysis.

Available Resources and Support

To assist volunteers in their efforts, several resources are available:

• A prospecting assistance guide is available, offering practical advice on where, when, and how to observe swallows and swifts.
• A flyer is available to help volunteers identify the different species.

For any questions or assistance, contact Julie COUTOUT. Additionally, pauline and Angie will be available for support during their internship from mid-May to the end of July, along with Emilie Wacker, who is in civic service.

The Plight of Aerial Insectivores: why Swifts and Swallows Matter

Across Europe, populations of aerial insectivores, particularly swifts and swallows, are facing unprecedented challenges. These birds, vital to our ecosystems, are experiencing significant declines, raising concerns among conservationists and ornithologists alike. Understanding the factors contributing to their dwindling numbers is crucial for implementing effective conservation strategies.

Swifts, known for their incredible aerial feats and almost constant flight, and swallows, with their graceful movements and association with summer, play a critical role in controlling insect populations. their decline has cascading effects on the habitat, potentially leading to imbalances in insect populations and impacting agricultural practices.

Habitat Loss and Climate Change: Key Drivers of Decline

Several factors contribute to the decline of swift and swallow populations. Habitat loss, driven by urbanization and agricultural intensification, deprives these birds of nesting sites and foraging grounds. Modern building practices often eliminate the nooks and crannies where swifts traditionally nest, while the removal of hedgerows and wetlands reduces the availability of insects, their primary food source.

Climate change also plays a significant role. Altered weather patterns can disrupt insect life cycles, leading to food shortages for swifts and swallows, particularly during the breeding season. Extreme weather events, such as droughts and heatwaves, can further exacerbate these challenges.

“The decline in insect populations, coupled with habitat degradation, poses a severe threat to aerial insectivores. Urgent action is needed to reverse these trends.”

Citizen Science and Conservation Efforts: How You can definitely help

Addressing the decline of swift and swallow populations requires a multi-faceted approach involving habitat restoration, lasting building practices, and community engagement. Citizen science initiatives play a crucial role in monitoring populations and gathering data to inform conservation strategies.

Organizations and conservation groups are actively involved in projects aimed at protecting and restoring swift and swallow habitats. These efforts include installing nest boxes, creating insect-friendly gardens, and advocating for policies that promote biodiversity.

You can contribute to these efforts by:

• Participating in citizen science surveys to monitor swift and swallow populations.
• Creating swift- and swallow-friendly habitats in your garden or community.
• Supporting organizations working to protect these birds.
• advocating for policies that promote biodiversity and sustainable growth.

Looking Ahead: A Call for Collective Action

The future of swifts and swallows depends on our collective action. By understanding the challenges these birds face and actively participating in conservation efforts, we can help ensure their survival for generations to come. Let’s work together to create a world where these iconic birds continue to grace our skies.

Throughout the year, we will suggest you discover these species, participate in their follow -up and act concretely for their protection!
