Introduction

The Black-necked Grebe is a master of discretion. Small, round, and silent, it glides through Japan’s winter waters like a living shadow. But catch it in spring plumage, and it’s a marvel: jet black feathers, ruby-red eyes, and golden tufts that shimmer like sunlight.

Appearance – From Jewel to Camouflage

This grebe wears two very different outfits depending on the season.

Breeding Plumage (Spring/Summer):

• Head, neck, and back deep black
• Golden, fan-like feather tufts behind the eyes
• Chestnut flanks, white belly
• Bright red eyes
• Short, straight, black bill

Non-breeding Plumage (Autumn/Winter):

• Grey back, white belly
• Blackish face, no tufts
• Red eyes remain but are less striking

One moment a royal showpiece, the next a master of disguise.

Habitat – Still Waters for Silent Divers

In Japan, the Black-necked Grebe is a winter visitor and migrant.

Preferred habitats:

• Quiet lakes and ponds
• Lagoons and slow-moving rivers
• Sheltered coastal waters
• Needs: clean, nutrient-rich water with good visibility

It avoids crowded or disturbed areas, seeking tranquil places to dive.

Diet – Precision Underwater Hunter

A true diver, the Black-necked Grebe hunts silently below the surface.

Main diet:

• Aquatic insects and larvae
• Small fish
• Tiny crustaceans

Hunting technique:

• Rapid, short dives using strong leg strokes
• Often seen diving in small groups
• Rarely rests at the surface – it’s almost always on the move underwater

The Black-necked Grebe does not breed in Japan.

Breeding areas include:

• Russia
• Mongolia
• Parts of Europe and North America

Breeding behaviour:

• Nest: floating platform of vegetation in thick reeds
• 3–5 eggs per clutch
• Both parents care for the chicks
• Young ride on the backs of their parents after hatching

Migration – Traveller Between Worlds

A long-distance migrant, the Black-necked Grebe arrives in Japan twice a year:

• Autumn passage: October–November
• Spring return: March–April
• Winter stay: until March on inland waters

Its migration route links northern Eurasia to temperate regions like Japan.

Conservation and Occurrence

In Japan:

• Not endangered, but locally uncommon
• Sensitive to water pollution and human disturbance
