Summer at the Marsh — Broods and Scouts of the Reedbeds

The marsh is in full breeding activity, and young birds are beginning to emerge.

Highlights:

  • Great Crested Grebe — adults carrying chicks on their backs, a magical moment
  • Kingfisher — intensive feeding of young, spectacular dives
  • Coot and Moorhen — families visible on the open water
  • Eurasian Bittern — still active in the reedbeds
  • Mass hatching: Reed Warblers and Reed Buntings feeding their broods
  • Lush vegetation — the marsh at its visual peak
  • Abundant dragonflies — naturalist interest extending beyond birds

Broad appeal: observing family behaviours (feeding, rearing), immersion in a dense and thriving habitat, and the opportunity to combine birdwatching with odonate observation for nature-curious visitors of all kinds.

Learn to spot and identify birds of the reedbeds, wet meadows and open water. Observation with binoculars, listening tips, and landscape reading along an accessible walk.

The Sacy Marsh is a world unto itself: rustling reedbeds, floodable meadows, ditches, copses… and a birdlife that shifts from hour to hour. This outing offers a guided discovery — both simple and captivating — to learn how to observe, listen and identify the species typical of wetland environments.

Along the walk, the emphasis is on good fieldcraft: where to look depending on the season, how to use binoculars and a spotting scope, recognising flight silhouettes, picking up on clues (calls, movements, behaviours), and understanding why a given bird favours one spot over another.

The outing is suited to beginners and those already familiar with birdwatching alike, in a friendly spirit: we take our time, we share, we progress. Bring boots (very wet terrain), weather-appropriate clothing, and binoculars if possible (tips will be provided on site).

What to bring: weather-appropriate clothing, comfortable footwear; binoculars recommended (rental available).

Naturalist Guide

As a naturalist guide, passionate amateur photographer, and ornithologist at heart, I invite you to walk at my pace—the pace of attentive observation.

My story is woven between France and Taiwan, two lands that shaped how I view nature: precise and analytical on one hand, deeply sensory and respectful of living things on the other.

Birds have led me along countless trails, my camera taught me patience, and it's this enduring enthusiasm that I'm eager to share with you today.
