Here's another look back at activities on the reserve from our local expert Ken Croft:
"The 2nd was a special day starting with a female Marsh Harrier hunting over heathland above the cafe fields, then at 0930hrs a male Monatagu's Harrier was quartering the lower slopes of the mountain. A good day for raptors and Peregrine and Kestrel are soon added to the day-list. A Common Sandpiper flew over calling and 2 Yellow Wagtails are feeding under the hooves of the Shirehorses, another appearance by the Hooded Crow and the day ends with the Montagu's Harrier hunting along the ridge south of Twr Reservoir.
The next morning the Montagu's continues to hunt the area and a Hobby is seen near Penlas Rock. The 5th sees the first Swifts flying over and next day 3 Spotted Flycatchers are new arrivals, there is no sign of the Yellow Wags but in their place are 9 White Wagtails. A Sparrowhawk flies over carrying some unfortunate "little brown job" and is quickly followed by a party of Whimbrel. The first Garden Warbler of the year is singing on the 8th and 2 Cuckoos are calling on the mountain slopes.
The 13th proves to be a lucky day when the 'rasping' call of a Corncrake is heard in a grassy meadow, it remains in the area until at least the 21st. Whilst listening to it calling in the cool of the evening on the 20th a flock of 16 Chough are doing cartwheels over Pen Y Bonc farm.
On the 22nd a party of 19 Arctic Terns are feeding off the lighthouse. The Hooded Crow makes it's final appearance on the 25th and a Black Guillemot flew north the next day. In the strong NW winds on the 27th a Storm Petrel was seen fluttering in the waves and Manx Shearwaters poured through at a rate of over 1000 per hour up to midday. The next day a Great Skua flew north."
