Je ne savais pas trop où poster ça, il me semble que c'est l'endroit approprié

Ancestral horses through the eyes of Charles R. Knight

http://wildequus.org/2015/07/25/ancestr ... -r-knight/

Charles R. Knight (1874-1953) was one of the most influential paleo-artists of all time. His depictions of prehistoric life forms make them come alive, gain character, and have sparked the imagination of many that view them.

The first time I came across his artwork, was in the cover of a book called ‘Bully for brontosaurus’ by Stephen J. Gould. But, his art not only depicted dinosaurs, many ancestral forms of horses also captured his imagination and he painted them on canvas for all to see.

As I was preparing this post, Rhoda, Charles Knight’s granddaughter, shared one of her childhood memories with me, and I thought I would share it with all of you.

Charles and his wife, Toppy and Nonnie (as they were called by Rhoda), lived in 24 West 59th street -New York City. On Fridays, Rhoda’s’ school let out early and she was taken in a taxi to the American Museum of Natural History to be with her grandfather, where they would spend the afternoons and many evenings. Rhoda remebered that Toppy would meet with many different scientists who all enjoyed being with him, and they discussed the latest findings.

From the museum they would typically go to Toppy’s studio to have dinner with Nonnie. Rhoda’s remembers that her bed was set up in the studio which looked out onto the avenue and Central Park south. From the studio window, both the west side and east side, with central park in the middle, were in view. Just across the apartment building they could see a dozen plus horse carriages lined up beside the side-walk. Every Saturday morning after breakfast, Toppy would walk Rhoda across the street towards these horses, walking from horse to horse- and Rhoda would stop and talk to each horse- pet it gently and hold out her hand with a carrot and some nuts.

Rhoda, loved those horses dearly, and would stand by them, watching them nibble the carrots from her hands and lick-up the nuts that she offered in a little cup. Toppy worried about these horses, and he visited them to be sure they were properly cared for. After the horse visits, Rhoda and Toppy would go to central park to spend the day at the Zoo- checking on each animal. Toppy worried about them all- he always wanted to be sure they were getting proper care and food!

After the typical zoo visits they would make their way back to the studio to help Nonnie prepare for tea parties! Toppy and Nonnie were always surrounded by friends, who loved coming to the Knight’s tea parties.

Rhoda remembers Toppy’s special love for these carriage horses, and of course the animals in the zoo.

These are the paintings of Charles R. Knight we have collected to share with you, with the kind permission of his granddaughter, Rhoda Knight Kalt.

Hier, en marchant de L'Axone de Montbéliard à la gare de Delle, j'ai vu, entre Dampierre-les-Bois et Badevel, un animal mort au bord de la route (sûrement une de ces nombreuses personnes qui ne respectent pas les limitations de vitesse).

Quelle est cette espèce ?

[Liya]

Il s'agit d'un blaireau FH. Famille des mustélidés, comme la belette, le putois et autres furets
Le blaireau est omnivore et creuse de très gros terriers.
Son habitat est très bien organisé, il a de petits WC à l’extérieur

L'espèce est considérée comme "nuisible" dans plusieurs pays: les chasseurs les tuent, il y a des campagnes d'abattage, et les automobilistes font souvent exprès de les percuter

[freeshost]

En quoi est-il nuisible ? Il pique nos assiettes ? Il transmet des maladies ?

[freeshost]

Au fait, devais-je le signaler ? appeler un numéro de téléphone ?

[Liya]

Le blaireau est accusé notamment de véhiculer la tuberculose bovine (notamment en Irlande/UK, où de grosse campagnes d'élimination ont lieu, cela a fait l'objet de protestations diverses et variées de la part des associations de protection animale et de certains citoyens)
Il peut aussi porter la rage dans les pays non indemnes, comme beaucoup d'autres animaux, sauvages ou non.

Sa mauvaise réputation est dûe en majeure partie, à mon avis, aux chapardages agricoles qu'il peut faire (céréales, fruits), à ses énormes terriers qui dérangent les agriculteurs, et à des légendes urbaines prétendant qu'il est agressif, tue des poules, des chèvres (!) et autres fantasmes / cas particuliers dépeints en généralités.

J'ai joué étant enfant très régulièrement à proximité de terriers "actifs" (il y en avait beaucoup chez mes cousins): je n'ai jamais aperçu le moindre occupant... alors se faire attaquer, je ris doucement (et jaune). Il doit falloir sacrément acculer la bestiole.

Edit: surement pas de signalement à faire, les agents de la voirie se chargeront d'évacuer l'animal lors de leurs patrouilles.

Ah ! ces personnes qui en font un bouc émissaire ! de vrais blaireaux !

J'espère qu'un jour j'aurai un microscope plus puissant qui me permettra de faire des photos avec une meilleure résolution que ce que je fais actuellement. C'est vraiment magnifique.

Est-ce que les blaireaux se laissent caresser ?

[Lilette]

C'est un animal sauvage, aucun intérêt
(sous-entendu, il est sauvage, moins il a de contact ac l'homme, mieux c'est).
