Comportement des Tadornes de Belon VS un intrus


Tadorna tadorna VS Egretta garzetta

Les adultes s'accouplent à vie et sont très protecteurs de leurs jeunes; la cellule familiale est très serrée. Pour inciter son mâle à la défendre, la femelle pointe le bec vers l'intrus et l'agite de droite et de gauche en émettant un cri caractéristique. À ce signal, le tadorne mâle attaque aussitôt l'intrus désigné.
Plus souvent pratiqué par les mâles que par les femelles, le rejet de la tête en arrière puis son maintien à la verticale, bec pointé vers le ciel en sifflant, est généralement un signal qui précède l'envol des oiseaux; pour des infos fouillées voir Larousse.

Common shelduck VS Little egret
The adults birds couple for life and are very protective of their young; the family unit is very tight. To get her male to protect her, the female points her beak towards the intruder and shakes it from right to left emitting a characteristic cry. At this signal, the male immediately attacks the designated intruder. Throwing the head backward and keeping the beak pointed upward whilst whistling is usually the signal to take off. Females choose males according to their degree of aggressiveness, hence their ability to protect her and the future chicks.
 


L'Aigrette ose passer entre maman et ses jeunes et ça ne plaît pas!



Se faire pincer les doigts d'aigrette par ce bec ne doit pas être agréable!




Mais quand elle pense en avoir fini, c'est papa qui fonce pour se débarrasser de l'intrus!





Bon, ce n'était pas si méchant, les jeunes tadornes sont capables de se débrouiller pour manger, ils sont à présent presqu'indépendants et trouvent très drôle de patauger dans la gadoue... agadou!!!

Wonderful series. I especially like the first image . . . certainly a territorial standoff,
but more like a "dance". Just beautiful.

Dramatic images Noushka. Those Shelducks can be quite mean customers.{:))
Cheers.

An excellent and very interesting illustrated account of the behaviour between the Egret and the Shelduck.

Mes salutations Noushka.

Bonsoir Noushka,
C'est la boue qui a noirci les pattes de l'aigrette ? Elles devraient être jaunes non ? Puisque le bec est noir j'en déduis que c'est une aigrette garzette.
J'aime bien voir les parents défendre leur nichée. Je ne l'ai pas vu en vrai chez les tadornes, nous n'y étions pas au bon moment sans doute.
Bisous et bon diamnche

Bonjour Noushka. It never ceases to amaze me just how fearless birds are in defence of their young, no matter the odds and the size of the perceived threat. Great pictures as always. Big hug.

Great images!!

Amazing that you managed to approach the shellducks so wel. With us they are very shy. Especially when they have got ducklings they are very careful. A littele egret I haven't ever seen in the Netherlands, but regularly in Africa. Great shots of both birds!
Greetings, Kees

L'un chasse l'autre, magnifiques photos!
Bon dimanche.

Richard Pegler a dit…

Your wonderful images tell a really heart-warming story, Noushka. It's wonderful to see the feisty Shelduck standing up to the egret, and to see the egret taking to its heels.

I hope your weather improves soon. We're cold but sunny at the moment, but it goes downhill tomorrow with heavy rain!

Love this series and Richard has said it all. I do love the reflections in the water as well. Think this must be one of the coldest Augusts on record; hopefully it will warm up before winter!
Have typed this now in a word document and will copy and paste it into comments to see if this works. Last and final try to leave a comment!! Diane

Fun series, Noushka! That Shelduck was not fooling around.. Both the egret and shelduck are beautiful. Awesome photos.. Have a happy day!

Breathtaking a dit…

Hello Noushka! Well, what a fabulous tale you have told here with your pictures. Somewhat amusing captures of both the Little egret and shellduck, but interesting behaviour of both, and ofcourse your photos are second to none.
Have a great Sunday
Best Regards.

Phil Slade a dit…

Spectacular action shots there Noushka. Those Shelducks really mean business don't they? I find it hard to photograph the white of Little Egrets, your balance is spot on.

Noushka a dit…

Thanks Phil,
I have switched to automatic ISO's, so I leave the camera manage by itself and it actually does a great job.
Since I've done that, I never looked back and I have much less problems with the balance except in very contrasted situations which are anyway very difficult to control...

Phil Slade a dit…

Very interesting Noushka. I always set my own ISO (Canon) but I will try Auto as you suggest. The problem here in the UK is very often poor light and so I try to avoid shooting at more than ISO800. Many thanks.

Marie a dit…

Great shots! That poor egret! Glad he was able to get out of the way! :-)

Corrie a dit…

Dear Noushka,
You've captured these story-telling pictures very well.
Brave shellducks. The egret looks very beautiful whilst hurrying away.
Best regards, Corrie
