Birds, flowers and wildcats in march.

After being snowing heavily during all February and have an historic snowfall, the rain came. The snow began to melt causing floods that were affecting localities of the midle and south of Navarre..
In this bend the Irati River flooded the road and was cut overnight.


Irati  riveer between Orbara and Aribe ( Aezkoa valley)
when the snow melted, the grass was been visible, and  herbivores went quickly to eat grass that was hidden.
When snow began melting
Deer grazing. Picture taken from the window of my house.

But the field mice ( Apodemus sylvaticus) and moles (Talpa europea) also took advantage of these days of tranquility to leave their burrows. The Wildcats (Felis silvestris) stand guard at the entrance of molehills or mouse burrows, waiting to attack minimal movement.
Sometimes, in the same meadow, I saw a fox, 4 deer and one wildcat.
On another occasion, I saw up to three Wildcats in the same field, and a fourth in the other side of  the Irati river.

Wildcat  (Felis silvestris)
Often  they are near from the villages, so, how can we recognize if there is a Wildcat  or common cat, at first glance, and from far away ?

  • Color: all  of them have earth color, to blend with the environment. Sometimes  they hybridize with domestic cats, and can be really difficult, if not impossible, know if they are  hybrids or not, from far away. If unfortunately we find one dead, there are typical design of dark stripes patterns on its back.
  • Tail: Much thicker than a domestic cat, has several broad dark rings, and the end with a black mark.
  • Size: There are more corpulent.
  • Behavior:  Always they are exceptions, but if it is a domestic cat let us come closer. If the wildcat is observed, and is relatively far, will tends to flee, and if we are too close, about 25 meters, often he sticks against  ground watching us, and if we have not seen him moving before, we can think it is a mound of a molehill, or cow dung.
This saw me

With snow are more visible.

Crouched, fixing his gaze in Me


But also March also brought a spectacular migration.
At first  the cranes came in a very good day, but the weather worsened again. Then,the white storks came, and some black storks too.

white storks in Ekai, near from Agoitz/Aoiz (Navarre)

White storks (Ciconia ciconia) on the way to the rest of Europa.
Somewhat later, on March 5, they also appeared in Orbaizeta, dozens of them.
 Older people commented place only once saw something in this village.







It happened that there were some badweather days, after having been rising temperatures and the birds that were already on the way, they met the Pyrenees covered with clouds, and decided to wait.
In the  Santiago´s way, at the crossroads of Auritz / Burguete the road to Garralda, We could see thousands and thousands of cranes circling above the meadows as deciding what they would do.

Eurasian stone- curlew (Burhinus oedicnemus)

Black stork( Ciconia nigra)
Days later appeared lapwings, little Egrets and some flocks of small birds that I could not identify.
little Egret (Egretta garcetta ) and lapwings in the bottom

Lapwing (Vanellus vanellus)


The flowers that you can see below, are usually the first year to bloom by mid-January, but this year have been delayed until the first week of March!
As I have said on other occasions, The snowdrop (Galanthus nivalis) is a rare survivor of the flora that we had here in the last Ice Age. When the ice move away to the north, most of the plants and animals typical of this climate were disappearing, but some of them resist, always close to the border of extinction.

Finally, a photo of the full moon of March. The winter sky is spectacular to see some constellations of this time as Leo or Orion, and have a clean atmosphere. Of course, dressed with warm clothings.

A sea of clouds


 Foggy downing Mount Ezkanda (Irati-Aezkoa)
Eastern Irati,  from Mount Mendilatz (Aezkoa Valley, Navarre)
There are no goats in Irati.  This is Belagoa valley , from the stone of St. Martin.(French border)
In summer is quite common to look the fog falling down when north wind (cold air) is blowing , and therefore heavier, spreads down the slopes to the south after the northern valleys of the Pyrenees have been filled fog.

Fog is not alwais dangerous. Can be beautifull-


The advance of fog to the south  isdepending of  the heat  that its find this on the southern slope,with hot air going up that tends to slow it when it is falling down.
In these photos, in the end of the day, hot air loses strength and when it cooled, begins to accumulate in the bottom of the valleys, as I have told, by the weight of the cold air.This is called termical inversion because in  normal circumstances, at higher altitudes, colder.
In the next day, when the sun rises and warms the air, the fog will tend to rise and disappear.
There is a great saying I heard that my great-grandmother, who says: "Fog in the morning , afternoon for walking"

Valle de Belagoa, valley with Larra on the left side.



Fog can be very dangerous if you do not know the terrain, and even if we know it. I know stories of shepherds who have spent the night in the open pasture lost by those who walk every day.
It is highly recommended to always carry a map of the area and a compass. If you carry GPS also much better, but do not confide everything to technology, because if this fails, you will see a serious problem.
If you like the exciting world of meteorology, I highly recommend this book. Besides good information, it's funny and readable:
