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.

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.

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.

This building sits not far from the Euston Road in the Fitzrovia area of London. It's got these wonderful curves as you see here but in amongst the curves are those rather odd shutters that point outward from the walls when opened. I quite liked the look of them.

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.
I first saw this behaviour earlier in the year. On that occasion the adult spent ages trying to get to the flesh of the starfish.
This youngster once it had seen off all it's rivals didn't mess about and simply swallowed the starfish whole.

This resident oriental pied hornbill was eyeing the newly furbished nest of the crested goshawk while his flock was nearby till the other eagle flew back...My first witness of such wildlife behaviour ..
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.
I made a quick trip to the nature reserve after work and met this beautiful and friendly girl. After moving to a very photogenic spot on the grass she spent several minutes turning, preening and generally showing off all her best sides for the camera! It was hard to pick a shot in the end :)
First is a Cinnabar Moth Caterpillar, next a Soldier Beetle, then a Ladybird and a Hoverfly. Please try viewing large. Thank you....

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.
Eared grebes have a variety of interesting bonding behaviours. I'm going to try to describe one of them. This images shows shows a single frame from a sequence (wish I had a video) where the male and female grebe face each other and are slightly puffed up. They vocalize, turn their heads, tilt their heads down and away from each other and do a quick bit of preening on their own neck area, face each other again, turn to the opposite side, and preen again. This is repeated a few times. Quite intriguing.

Some male birds will bring food to a female as part of courtship to show he can provide for any chicks she may produce. He may simply bring the food for her to eat or in some cases actually transfer it directly to her mouth just as he would to hungry nestlings.
