A great day's birdwatching today started with the bubbling calls of lekking Black Grouse accompanied by the songs of Tawny Owl, Grasshopper Warbler, Cuckoo and Curlew. Later, many of my favourite sounds of spring were added including the songs of Tree Pipit, Wood Warbler, Redstart, Pied Flycatcher and Common Sandpiper. Highlight of the day was watching Red breasted Merganser (probably my favourite duck species) on Loch Lomond in beautiful viewing conditions. Species showing evidence of breeding behaviour included a Wren entering a nest, a Blue Tit feeding a fledged juvenile and two Chaffinches, two Song Thrishes and two Grey Wagtails gathering prey items from the path. Plant species in flower consisted of Dog Violet, Lesser Celandine, Bluebell, Stitchwort, Herb Robert, Wild Garlic, Primrose, Wood Sorrel, Cuckoo Flower, Golden Saxifrage and Marsh Marigold. Butterflies were represented bty two Orange Spots.
