PORTOBELLO HARBOUR 21 SEPTEMBER 2024

Two students from Africa were enjoying a peaceful moment feeding pigeons and seagulls at Portobello Harbour when they were startled by an unexpected visitor. A large heron landed beside them, seemingly eager to join the feast. The girls were thrilled by the encounter, but the seagulls were less than pleased by the intrusion.

Such boldness from a heron might seem unusual, but it’s not entirely unheard of. Herons are intelligent and adaptable birds, capable of learning that humans can be a source of food, especially in urban areas. They are opportunistic feeders, always on the lookout for an easy meal, and some individuals might be naturally bolder than others. In places where people regularly feed birds, herons can become habituated to human presence and associate people with food.

Identifying the Grey Heron

The heron in question was most likely a Grey Heron, a common sight in Ireland. Here are some key features to help identify them:

Size: Grey Herons are large birds, standing about 90-100 cm tall with a wingspan of 1.7-1.9 meters.
Coloration: They have predominantly grey plumage, a long white neck, a black stripe above the eye, and a striking yellow, dagger-like bill.
Silhouette: In flight, they have a distinctive hunched posture with their neck tucked into an ‘S’ shape and their long legs trailing behind.
Habitat: They are found near wetlands, rivers, lakes, and coastal areas, often standing motionless at the water’s edge while hunting for fish.
Call: Grey Herons have a loud, harsh “fraaank” call.
Nesting: They often nest in colonies called heronries, high up in trees.

Birds that might be confused with a Grey Heron include the Little Egret (smaller and entirely white) and the Crane (larger with a longer neck held straight in flight, less common in Ireland).

While it’s generally not a cause for concern if a heron approaches you, it’s important not to feed them directly. This can lead to dependency on humans for food and disrupt their natural foraging instincts. Admire these magnificent birds from a distance and educate others about the importance of not feeding them.
