Whooper swans in Carrigeencor lake

Whooper swans are regular visitors to Carrigeencor lake (Dromahair, Co. Leitrim). They usually come in small numbers, but large groups like this one can also be seen sometimes. In this particular occasion I counted 21 swans.

The Orange-tip (Arthocharis cardamines) is one of the first butterflies to appear in the spring. Here, in Manorhamilton (Ireland), they're on the wing from April until early June. The male, being territorial, can be seen incessantly fluttering about in search of female and warding off other males. I have even seen them chasing off members of other species, in particular, Small white (Pieris rapae) and Green-veined White (Pieris napi britannica), which, like the Orange tip, are members of the Pieridae family.
The bright orange wing tips, which gives the butterfly its name, probably serves as a display to attract females and as a deterrent to other males.
The female, in contrast, keeps a low profile. Her wing tips are black, instead of orange, and can only be seen flying when feeding or searching for plants to lay her eggs on.

Both male and female are very flighty and hard to approach, as the slightest movement will set them off. The best time to get close to them is when the weather is not good enough for them to be active. At this time they can be found resting on plants, with a preference for those with light colour flowers. When at rest, the butterfly will keep its wings closed, so only the white and green under-wing is visible. This helps them blend with the environment, while their asymmetrical green pattern helps to break their silhouette, giving the butterfly pretty good camouflage against predators.

 The two most common plants where you can find their eggs are Ladies' Smock (Cardamine pratensis) and Garlic Mustard (Alliaria petiolata). I have observed a strong preference for Ladie's Smock, except for one site were there was a higher proportion of eggs on Garlic mustard. Several eggs can be seen in a single plant at different stages of maturation. I have often wondered whether they're all laid by the same female or by different. A recent sighting of a female who, after actively searching through a patch of flowers for over five minutes, went off without laying any eggs, leads me to think that they possibly avoid laying their eggs in plants where eggs from other females are already present. This would make sense, as the caterpillars are said to be cannibalistic, so the eggs of any butterfly that are laid in a plant that already has eggs would be doomed, as the caterpillars from the first eggs would hatch sooner and eat the late arrivals.
Despite much searching, I still haven't been able to find any caterpillars, even when I have returned to look in plants where I had found eggs.

The Cinnabar

The Cinnabar (Tyria jacobaeae) is a colourful day flying moth belonging to the Arctiidae family. It can be found in any grassy habitat where it's larval food plant, Ragwort, available.  Indeed, I have seen it in such diverse habitats as coastal grassland, forests and waste grounds.
Despite it's bright colours it can be hard to spot when hiding amongst the vegetation with it's wings closed, and only becomes conspicuous during in flight when its red underwings are in full display.
The caterpillar, with its yellow and black stripe, is even more conspicuous than the adult and can be found in large numbers devouring Ragwort. Their voracious appetite make them a natural and efficient means to control this plant.

Dandelion- the wonder food

 Every spring my garden gets covered in a carpet of Dandelions. Being one of the earliest plants to flowers, it attracts a wide variety of butterflies, bees and hover-flies that have just emerged from hibernation and are in much need of a rich source of nectar. 
The seeds of Dandelion also provide food for birds such as finches. In my own garden I've seen Gold finches and Bull finches feasting on this food source.
Below is a selection of photos, that I have taken over the years , showing insects feeding on Dandelions.

Feeding the birds

At this time of the year, when there's not a lot of wild food around, our feathered friends can do with any extra help. Having a variety of foods will ensure to cater for the needs of different types of birds.
Having feeders also offers a great opportunity for bird-watching from the comfort of your own house. It is always quite exciting to see a new species come to your garden, or to see a previously lonesome bird feeding in the company of a potential mate.
Don't forget to have a source of liquid water on frosty days when most water sources might be frozen.

A Greenfinch feasts on peanuts, a great source of fat which is particularly important in the winter. 
One of the Goldfinches is feeding on Niger seeds, a favorite of them, while the other settles for the mixed-seed. The Tit family, such as the Great Tit and Coal Tit in the photo, love sunflower seeds.

This family of Bullfinches came for the remain of the Blackberries. Having plants that produce edible fruits and seeds will also encourage  birds to your garden. 
Initially only one of this Lesser Redpolls  was visiting the feeders, but it was later joined by another one. The two of them are now regulars.

First Primroses of 2013

The mild weather we've been having for the last few weeks have brought this Primroses into bloom, but a sudden frost will probably put an end to the emerging flowers. Even if they survive the frost it will be pointless, as far as the plant is concerned, as there is no insects about to pollinate them.

As I was walking back along the same road, I spotted two small Dandelions that had joined the Primroses in their futile effort to flower at this time of the year.

Apologies for the bad quality of the photos, but it was getting dark and the flash didn't work well with the flower shots
