Observing migratory birds in Ba Be National Park
Every winter, Ba Be National Park hosts a relatively unknown natural spectacle for visitors: the massive arrival of birds fleeing the Siberian and Northern Chinese frosts. Follow our guide to explore this gem of Vietnamese biodiversity.
A sanctuary between lakes and forests
Globally recognized as a Ramsar site (internationally significant wetland), Ba Be is more than just a picturesque lake. It’s a mosaic of habitats where karst forests, mangroves, and rivers coexist.
Out of the 320+ bird species recorded, around fifteen rare migratory birds choose these unfrozen waters to spend the winter. Among the park’s stars are the elegant Mandarin Duck, the Northern Pintail, and the critically endangered White-eared Night Heron.
Why is Ba Be a birding hotspot?
- Strategic geographic position: The valley acts as a natural corridor between the Yunnan Plateau (China) and the Red River Delta, turning the lake into an ideal migratory stopover.
- Habitat mosaic: Subtropical moist forests, marshes, terraced rice fields, rocky outcrops—various ecological niches side by side.
- Mild dry season: From October to April, mild temperatures (15–24 °C), morning mists, low precipitation—perfect conditions for morning birdwatching.
Migratory season calendar
The season runs from October to April. Two types of travelers can be spotted: those who settle for the winter and those just passing through.
Periode | Key species | Phenomenon |
October – November | Mainly Northern Pintail | Arrival : First migrants arrive from Siberia |
December – January | Mandarin Duck, White-eared Night Heron | Wintering : peak numbers. These species stay all winter. |
February – March | Large waders (Grey Heron, Black-crowned Night Heron) | Transition : Birds gather before heading north. |
April | Indochinese Roller especially | Passage : Brief stopover for the latest “latecomer” |
A morning immersion with Mr Linh’s Adventures
To approach these species without disturbing them, local expertise is essential. Here’s what a typical morning looks like.
- 05:00 – Lake Awakening: Briefing over Vietnamese coffee at the Pac Ngoi bridge. Binoculars check (8×42) and eBird checklist.
- 05:15 – Silent Glide: Boarding an ultra-silent electric motor canoe. Head to Dau Dang Bay, where the water is a perfect mirror.
- 06:30 – Forest Chorus: Disembark for a walk in the understory. This is where you search for Red-bellied Trogons and Barbets hidden in the canopy.
- 07:30 – Drongos Ballet: At Phuong Pass, observe the acrobatic flights of Drongos (recognizable by their forked tails) hunting insects on the wing.
- 08:30 – Review and Share: Return to the village for ginger tea. Tally the species seen (often over 25 in a morning!) before sending the data to the eBird scientific base.
