A delightful small, long-tailed and rather sprightly black and white bird. When not standing and frantically wagging its tail up and down it can be seen dashing about over lawns or car parks in search of food. It frequently calls when in its undulating flight and often gathers at dusk to form large roosts in city centres

Long-tailed Tits are delightful birds to encounter, swinging through the trees in tight noisy groups. Their appearance, like a tiny, fluffy ball with a great long black and white tail is quite unmistakable. Breeds in dense vegetation on woodland edges, scrubby thickets and hedgerows. Occurs more widely in winter including woods and gardens. The constant calls of Long-tailed Tits are to help the flock stay together. If one bird gets separated from the rest of the flock, the others will double-back to 'rescue' it. This means that if you can imitate their calls you can attract a flock to within a few feet of you and it also explains why ringers sometimes find that a mist-net full of Long-tailed Tits often contains birds which have entered from both directions. This apparent 'care' for the well-being of other members of the flock is almost certainly related to the fact that many flocks are in fact family parties of closely-related individuals.

The adult Ring-billed Gull Larus delawarensis is a medium-sized gull, measuring 45 cm from bill to tail, having a 50-cm wingspan and weighing about 0.7 kg. Its white head, neck, underside and tail contrast with its grey wings (or back when the bird is at rest). The wing-tips are black with white spots and the legs and feet are yellow-green. A black ring encircles its yellow bill near the tip.

In appearance the adult Ring-billed Gull is similar to the Herring Gull, but the Herring Gull is bigger and has flesh-coloured legs and feet and a red dot on the lower part of the bill rather than a black ring.

Young Ring-billed Gulls are a mottled brown, much different in colouring from the adults. With each successive moult, or shedding of old feathers, they lose more of the brown and develop more of the white, grey, and black patterning.

Ring-billed gulls range from southern Alaska to the north shore of the Gulf of St. Lawrence, to southern parts of Oregon and Colorado and northern New York. During the winter, it is found from British Columbia to Maine (including the Great Lakes and Maritime regions), then south to central California to southern Mexico to the Gulf Coast to Cuba. It is also found in Bermuda and Hawaii. This gull winters from southwestern British Columbia and Washington state to the Great Lakes region to Nova Scotia then southward.

This one was photographed in Cuskinny Marsh in Cobh

The biggest dragonflies found in Ireland are the Emperor Dragonfly (Anax imperator) which are between 7 and 8cm (3-3.5 inches) long. Emperor Dragonflies are spreading into Ireland due to population expansion in Europe and changing climate. The Emperor Dragonfly was first recorded in Ireland as recently as 2000.

Males have a sky blue abdomen marked with a diagnostic black dorsal stripe and an apple green thorax (as shown above). Females have a green thorax and abdomen. The male is highly territorial, and difficult to approach. The species lives by larger ponds, gravel pits, and slow rivers.
