Summer Breeding: Islay's Bustling Birdlife

Islay's summer months are abuzz with the vibrant and energetic activity of the island's diverse bird population. As the breeding season kicks into full swing, Islay becomes a hotbed of avian activity, with several breeding hotspots scattered across the island. These hotspots, such as the RSPB reserve at Loch Gruinart and the reedbeds at Loch Indaal, provide the perfect conditions for birds to establish their territories and build their nests.

One of the most fascinating aspects of Islay's summer breeding is the unique nesting behaviors exhibited by different bird species. Take, for example, the majestic common sandpipers. These birds, known for their distinctive white bellies and long bills, have a peculiar nesting strategy. Instead of building nests on the ground like most birds, they construct their nests on elevated platforms made of twigs and leaves. This ingenious adaptation helps protect their eggs from potential flooding during high tides.

Another interesting species with its own peculiar nesting behavior is the red-throated diver. These magnificent birds, with their striking red necks and haunting calls, build their nests on small rafts made of floating vegetation. This not only provides them with a stable platform but also keeps their eggs safe from predators such as foxes and stoats.

Observing Islay's bustling birdlife during the summer breeding season is a true spectacle. The island's breeding hotspots and the unique nesting behaviors displayed by its avian inhabitants make for a captivating and educational experience.

As summer comes to an end, the air on Islay becomes filled with anticipation as the time for autumn migration arrives. The summer residents, who've spent the breeding season on the island, now prepare to embark on their long journeys to their wintering grounds. The migration routes they take are determined by a combination of genetic programming and environmental cues, such as weather patterns and availability of food along the way.

The autumn migration on Islay is a spectacle to behold. Flocks of birds gather in large numbers, creating a mesmerizing sight in the sky. The population dynamics during this time are fascinating to observe. Some species, like the Arctic Terns, leave in large groups, while others, such as the Swallows, depart in smaller numbers.

The departure of the summer residents marks the end of a vibrant and bustling period on Islay. Their absence leaves a void, but it also signals the arrival of new visitors – the winter migrants.

Islay's wintering birds also have an ecological impact on the island. They contribute to seed dispersal and pollination, aiding in the regeneration of plant communities.
