Bird Behaviour in Action
View allAll Photos Tagged behaviour
the horbills are quite large birds used to feed on fruit and mainly insects,arachnids and small vertebrates.
but they are not used to kill aduld birds.
in this case an African Grey Hornbill (tockus nasutus) has cought and killed a social weaver.

================
NORMALLY VERY PLACID HERON, with no neck showing, but something came near, did not see what it was, it reeled out its neck , with a feather duster look, with a loud grunting type call, was quite taken back with its very long neck behaviour. Have shown the normal pose thirty seven images back, if you want to compare

I was observing a group of sea gulls next to the Yarra River when I took this shot.
I am sure you would have seen these postures and calls before.
I was also curious about these postures and their meanings.
Here you can see two common postures.
The gull in the front is showing the Forward Posture.
As the name implies, this posture is all about displaying a forward motion by holding the body roughly horizontal or slightly diagonally with the neck kinked characteristically.
The tail can sometimes be spread; the bill is either slightly opened or closed.
The Forward posture is used in the following situations:
1) hostile encounters
2) pair formation sequences
3) as a response to a bird approaching in flight
When used in hostile encounters on land, it often includes running towards an opponent, whereas in a pair formation sequence both gulls move parallel to each other
The Gull behind is doing the Mew Call
The Mew call is accompanied by a characteristic Arch-posture in which the head is held down and the wings are held slightly away from the body.
It is usually performed while walking but can be performed while standing, flying, or swimming as well.
The Mew call is used in both aggressive and non-aggressive situations:
Aggressive
1) In defense of food or territory, aimed at an opponent
2 )To attract a mate for support in territory defense
Non-aggressive
1) To attract a partner (also for courtship)
2) To call chicks that have wandered too far from the nest
3) To gather chicks for feeding or after they have been hiding after a disturbance
4) As a nest-relief invitation
5) As a call performed upon landing.
Many thanks for your visit, comments, invites and faves...it is always appreciated...

From the "senses" series: Vision
If someone sees something, they react. Cause-effect. According to Pavlov, reflexes could be conditioned. If you don't see, you don't react. But if vision is deprived from you and you know and watch that you don't see because someone doesn't want you to see, you react. Cause-effect.
One of the pair of bridled common murres show here has just arrived back on a ledge of the nesting cliff, so a little vocalizing, mutual pecking, and wing flapping was in order.
Feeding behaviour - Typically forages in shallow water. Often feeds very actively, sometimes running after minnows. May forage by walking forward while swinging its head back and forth with the tip of the bill in the water.
AHP East, Ottawa.
Stag frantically digging up mud at the edge of a lake to cover its antlers before dressing them in vegetation. Not sure if this is to impress the ladies or threaten other males in the rut.
Puffins mating and courtship ritual, the puffins will pair up before they come onto land from the sea. Once they are on land, the pair may perform billing, a behaviour where puffins rub their beaks together. There numbers are falling because of global warming and this year bird flue.
Not sure what,s going on here.At first i thought the ants were moving their larvae to another location,but the first larvae is clearly a plant hopper nymph! So moving plant hopper larvae for security,or food?
Thanks for your comments and faves,they are truly appreciated.
First is a Cinnabar Moth Caterpillar, next a Soldier Beetle, then a Ladybird and a Hoverfly. Please try viewing large. Thank you....
Barrow. Très abondant mais je n'ai pas insisté vu qu'on en a des tonnes à Montmagny, entre autres, avec un plumage équivalent. Everywhere on the wet toundra. Nuptial behaviour. Nice song.
I was watching a group of Harbour (Common) and Grey Seals hauled out on the beach at Horsey, Norfolk during the first week of June when a big male Grey Seal caught my attention at the water's edge. It seemed to be holding down another smaller seal and when other seals approached it behaved aggressively towards them. The struggle continued for some time but the malevolent looking big bull clearly had the upper hand. Nov. - Dec. is the breeding seasons for Grey Seals on the east coast towards the latter part of which time male/male competition can be intense. This behaviour was, therefore, very unusual in that it was seen at a time of year when Grey Seals should not be competing (or mating). My thanks to Tim Melling for his explanation and interpretation concluding that the big size difference makes it likely that this behaviour was probably sexual aggression towards a non willing female.
This building is the work of two former students of Mies Van der Rohe. It shares the basic concepts put in practice by Mies in many of his buildings, but in this case the structrure is covered by a pronounced, curved skin.
