At this time when we are enjoying the longest days of the year, most of the animals are working en masse: kilkirrak in their eagerness to attract reproducing singers, many other children, etc. The increase in temperatures is accompanied by a large number of crickets and other insects and invertebrates. In addition to beautiful butterfly bugs, txitxiburduntzi, ladybug and similar, anywhere you can find ticks, control flies or mosquitoes that we do not like so much. However, from these invertebrates a large number of animals are fed, all of them of great importance in the ecological pyramid.

Spring has also reached the Pyrenean helmets and has been filled with beautiful flowers. Finally, local pastors can also ascend to the superior pastures. As for the south, the wheat fields have begun to yellow and the cherry trees are full of fruit. In the streets, at the gates of the summer, it's time to start preparing the pants, skirt and short t-shirts. Metamorphosis of the skewer

The behavior of the txitxiburduntzis larvae in the town regatta is surprising in recent days. And, although they eat normally, lately they have no snack and you can see that something is about to happen. Suddenly, one of them emerges and gradually ascends in a reed. It seems that oxygen has begun to breathe!

Listen to the reader, that our aquatic larva prepares to land! When he's in the reed, a crack has been made in the back and a whitish body has begun to appear (in the most expensive movies of the aliens there are no scenes of this type! ).

It took a couple more hours to disassemble this old deck and open two pairs of fins. Hours earlier, the aquatic larva has become a skewer of vivid colors that flies through the river. Goodbye! Snake to the vera

For the misfortune of snakes, with a warm atmosphere it is not usually difficult to find a snake. In Mediterranean Ixurialde, for example, it is easy to see the Montpellier snake. This quick snake is poisonous, but its canines are inside the mouth and it is almost impossible for a person to introduce poison. However, even if this poison is inserted, it is not very effective for the human being. But to dominate mice and other small animals that hunt reptiles is great. So, just reach a little mouse and start to swallow, with these fangs from the back of the mouth, puts poison to facilitate the tasks of belly and digestion.

Change of wardrobe

Although they are usually not very colorful, sometimes snakes are seen with little color. This feature indicates that the skin is about to change and stops eating snakes. Little by little, under the old one develops the new and when the leather is about to change it takes a bluish color. At any given moment the breach is opened around the lips and with this swollen hole he takes his head. Thanks to the movements of the snake, just as a glove is removed from the hand, it disappears the aged leather and, having a new way of dressing below, we are presented with a snake of vivid colors.

The process seen, the renewal of the leather, that is, the snakes do 5-6 times a year. Amphibians also alter the skin, the same happens with the outer cover of invertebrates. Something similar happens to humans after burning us to the sun.

Hill of birds

Just as the snakes restore the skin, the bird feathers are also aged and, of course, they must also be modified. By falling all the feathers at a time, they would lose their ability to fly, so they change them little by little and in a given order. However, many duck species, when they do, are left unable to fly for a few days, so they should go to appropriate wetlands. The change of feathers has a great energy need and, of course, birds do it at the time that suits them best. Many renew it after breeding and thus, by the time the time of migration arrives, they have ready the new plumage.

Amiltxoris in Las Cañas

Amiltxoris are nocturnal birds of the heron family, despite being relatively small compared to them. They live in wetlands and adapt perfectly to dense vegetation. Nothing more darkened, the birds have the time to eat and are the animals that hunt the most, the aquatic insects, the crustaceans and the small vertebrates. After spending the winter in Africa, they return in April to reproduce. In Euskal Herria we have famous colonies of birds. In Lapurdi, for example, there is a beautiful colony on the islands of the Aturri River opposite Lehuntze, Urketa and Ahurti. In Navarre it grows in forests located on the banks of the Ebro and Aragón rivers, and especially in the lagoon of "Las Cañas" of Viana. Added to the latter, Navarre has more than 325 couples.

Vaults in the south of Navarre

These are vaults, steppes and birds of dry areas that live mainly in the Basque Country, the Bardenas and in the nearby plains. They have the size of the doves and are perfectly adapted to live in these dry and warm regions. In our territory there are two species of vaults: the cross vault and the sirloin. Both are very scarce and although there can be about 800 specimens of the first one, it is estimated that the population of the cruising vaults of Navarre ranges between 400 and 700 specimens, so it is very small. These birds, having to drink water almost every day, frequently resort to wells and rivers. The chicks also need water and the vaults carry them in a very special way during breeding. Parents when they drink meten their chest in the water to collect a few drops of water in the pen. Then, at a glance, the chitones are given to hold them.

Hare, as discreet as suspect

Today, in search of the first owls of the year, we have met a child on foot. Fairy and sinkhole, by not appearing any mother, we have been tempted to bring the crazy to the house. However, in the end we decided to leave him there and thank you, because his mother was not going to be far away.

The hare is a prudent animal. After childbirth and during the month of breastfeeding, the mother often distributes the young. Each one hides in a given place and he will give the milk one by one. This behavior may increase the risk that enemies will find some breeding, but it also increases the chance that a child will move forward. In addition to babies, at this time you can find offspring of many other species: chorizos, deer... But eye! Although they appear lost and unprotected, most of the time the mother is not usually far away. However, if we pick her up by hand, she can scare her mother and dare not care for her children. In addition, if we get the offspring to take home and grow, releasing them would hardly adapt to their way. So, think twice before a child gets home.
