Light buzzards’ colorations and migration – 03

– Accipitriadae – This is the lightest buzzard I saw so far this winter. Easily recognizing individuals thanks to the plumage coloration of their breast and comparing them from one season to another has proven me that I have not seen again the birds from previous years, which implies that they do not develop habits where wintering is concerned, as long as they reach temperate areas to survive through winter.

C’est la buse la plus claire que j’ai pu voir jusqu’à présent cet hiver. Comme l’avons vu dans l’article précédent, ces buses plus claires viennent des pays nordiques et sont donc étroitement liées à la . Reconnaître les individus par les plumes du poitrail et les comparer d’une année sur l’autre m’a prouvé que pour le moment je n’ai pas revu les migratrices des années précédentes, ce qui implique qu’elles n’ont pas d’habitudes quant à un lieu d’hivernage précis, du moment qu’elles se retrouvent dans des zones tempérées pour survivre à l’hiver.

Buteo buteo

More robust and heavier than other birds of prey in southern areas, this buzzard has a rather heavy flight compared to that of kites – red or black – or Sparrowhawks but nonetheless, it shows itself swift when needed.

As kestrels it can also hover above a prey but it is not all that frequent, hawks having made this particular mode of hunting a specialty.

Plus trapue et plus lourde que d’autres rapaces de nos régions, cette buse a un vol assez lourd comparé à celui des milans ou des éperviers mais elle n’en reste pas moins agile pour autant.Comme le Faucon crécerelle, elle peut aussi faire du surplace (le St esprit) au-dessus d’une proie, mais ce n’est pas aussi fréquent, les faucons en ayant fait un mode de chasse bien particulier.

On the other hand, it looks for ascending aerial currents to move to other areas in search of prey; it will often be seen diving into a bush or hedge with its prey to consume it away from other preying eyes.

Par contre, elle cherche les courants ascendants pour se déplacer et monte haut pour changer de territoire à la recherche de proies; souvent elle embarquera sa proie dans un fourré à l’abri des regards.

Buteo buteo

Coming from northern Europe, its wingspan allows it to glide effectively during migration and reach an altitude of 1000 m and more. It travels usually alone but a few individuals can join in to take advantage of favorable currents.

Nowadays less and less of these birds cross over the Pyrenees mountains and numbers in the south-west can rise pretty much.

Venant d’Europe du nord, la taille et l’étendue de ses ailes lui permet de planer efficacement à la migration et d’atteindre une altitude de 1000 mètres voire plus. Elle voyage de jour souvent seule mais parfois plusieurs individus peuvent se rejoindre, profitant des courants aériens favorables. De nos jours, de moins en moins de ces oiseaux passent les Pyrénées et leur nombre s’accroît l’hiver dans tout le sud-ouest.
