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

Lesser Tenrecs will self-anoint/nuzzle or "scent-mark", usually after vivarium cleaning, introduction of new objects like in this situation, but they will also self anoint on parts of a human body such as the hand.

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...

Black Redstart - Phoenicurus ochruros (M)
The black redstart (Phoenicurus ochruros) is a small passerine bird in the redstart genus Phoenicurus. Like its relatives, it was formerly classed as a member of the thrush family (Turdidae), but is now known to be an Old World flycatcher (Muscicapidae). Other common names are Tithy's redstart, blackstart and black redtail.
It is not very closely related to the common redstart. As these are separated by different behaviour and ecological requirements.
It is a widespread breeder in south and central Europe and Asia and northwest Africa, from Great Britain and Ireland (where local) south to Morocco, east to central China. It is resident in the milder parts of its range, but northeastern birds migrate to winter in southern and western Europe and Asia, and north Africa. It nests in crevices or holes in buildings.
In Britain, it is most common as a passage and winter visitor, with only 20–50 pairs breeding.
On passage it is fairly common on the east and south coasts, and in winter on the coasts of Wales and western and southern England, with a few also at inland sites. Migrant black redstarts arrive in Britain in October or November and either move on or remain to winter, returning eastward in March or April. They also winter on the south and east coasts of Ireland.
The species originally inhabited stony ground in mountains, particularly cliffs, but since about 1900 has expanded to include similar urban habitats including bombed areas during and after World War II, and large industrial complexes that have the bare areas and cliff-like buildings it favours; in Great Britain, most of the small breeding population nests in such industrial areas.
Population:
UK breeding:
19-44 pairs
UK wintering:
400 birds
Dove and Red-headed Finch.

This very small nutria was walking silently in the shadow, that's why I had to use high ISO. Zoom in for more details.
As you can see his fur has a lot of different shades of brown.
And as you can see he was very young : big head and small body

Grackles, and some other species in the same family, have the habit of sitting still and pointing their beaks up, like they are surveying the sky. From what I've read, this behaviour is really about establishing dominance during the mating season. He who points higher wins! Don't know if it is really that simple, but it is an explanation.
It is not just the boys that enjoy singing in the springtime.
However, the tune and the volume is a little softer.
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.
Taken a few months back in the Kent coastal town of Whitstable. In general seagulls in the British coastal resorts have a bad reputation for their aggressive behaviour, well deserved I should add. Should you just be tucking into your lovely bag of chips (fries) you'd better beware that if you take your attention away for even a second then chances are one of these guys will be swooping in for a free meal. It can scare the bejesus out of you! And if they don't steal your food they just might leave you with something else in the form of an embarrassing white streak down your back, or heaven forbid, on your head!

I'm going to be leaving this message on my next few posted images. This is to let the photographers that I follow know that due to the immense amount of time it takes me to go through all the photos that appear in my Flickr stream each day I am setting my stream to show only one image per day per person. It's either that or get Flickr burn-out. Apologies in advance if your photos don't get as much of my attention as they used to. Hopefully people will understand my reasons for doing so. Thanks.
This juvenile is very different from the others.
He has always eyes closed
He is all white
He always stay hidden (very hard to do few photos)
This is the first Albino Nutria that I have ever seen.
Saddly the only opportunity I had to see this animal was during a bad end of afternoon.

Courtship behaviour of the great crested grebe.
great crested grebe
Haubentaucher
[Podiceps cristatus]
Common redshanks in breeding plumage are a marbled brown color, slightly lighter below. In winter plumage they become somewhat lighter-toned and less patterned, being rather plain greyish-brown above and whitish below. They have red legs and a black-tipped red bill, and show white up the back and on the wings in flight.
Mud-puddling is a feeding behaviour displayed by butterflies. Although they primarily feed on nectar they seek out other essential nutrients including minerals and amino acids in moist substances such as rotting plant matter and mud. Where the conditions are suitable, butterflies form aggregations while mud-puddling.
There are six species of butterflies in this photo taken at Phnom Kulen National Park, Cambodia. I have identified two species. The large butterflies are yellow helens, Papilio nephelus. The white butterfly in flight is the same as the yellow and white butterflies with a dark edge at the edge of their wings. They are chocolate albatrosses, Appias lyncida.
Thanks for visiting. I am very grateful to those who take the time to comment or fave.
Spyder turning his head upside down as I sweet talk him into taking his photo, behaving ever so bashful!

One side of Timmy is the adventurer: today a wall was newly concreted at the construction site at the creek behind the house. Two hours later Timmy checked the quality of the work. Fortunately, the concrete was already solid enough so that he did not leave paw prints :-)))

To me, darters always look happy, and this cheery-looking chappy is no exception.
The farmer helpfully dug a small pond next to our house about two years ago, and the common darters didn't take long to find it (also saw common hawker this year!).
I do find these very tricky subjects, because they are either zipping about and never landing (when it's sunny), or completely hidden (when it's cooler). In my few attempts, I haven't found any willing to pose this year ... so here's a shot from last September of a male resting on a post.
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 :)
Meg & Jess, I still miss them, we walked through life together for some 14 years, I did research into their obvious behaviour's but most of all I grew to love them, I miss them both dearly,,......Best Wishes Tim.
First is a Cinnabar Moth Caterpillar, next a Soldier Beetle, then a Ladybird and a Hoverfly. Please try viewing large. Thank you....
Siskin - Carduelis Spinus
The Eurasian siskin (Spinus spinus) is a small passerine bird in the finch family Fringillidae. It is also called the European siskin, common siskin or just siskin. Other (archaic) names include black-headed goldfinch, barley bird and aberdevine. It is very common throughout Europe and Asia. It is found in forested areas, both coniferous and mixed woodland where it feeds on seeds of all kinds, especially of alder and conifers.
These birds have an unusual migration pattern as every few years in winter they migrate southwards in large numbers. The reasons for this behaviour are not known but may be related to climatic factors and above all the availability of food. In this way overwintering populations can thrive where food is abundant. This small finch is an acrobatic feeder, often hanging upside-down like a tit. It will visit garden bird feeding stations.
These birds can be found throughout the year in Central Europe and some mountain ranges in the south of the continent. They are present in the north of Scandinavia and in Russia and they over-winter in the Mediterranean basin and the area around the Black Sea. In China they breed in the Khingan Mountains of Inner Mongolia and in Jiangsu province; they spend summer in Tibet, Taiwan, the valleys of the lower Yangtse River and the south east coast.
The Eurasian siskin is occasionally seen in North America. There is also a similar and closely related North America counterpart, the pine siskin, Spinus pinus.
heir seasonal distribution is also marked by the fact that they follow an anomalous migration pattern. Every few years they migrate southwards in larger numbers and the overwintering populations in the Iberian Peninsula are greatly augmented. This event has been the object of diverse theories, one theory suggests that it occurs in the years when Norway Spruce produces abundant fruit in the centre and north of Europe, causing populations to increase. An alternative theory is that greater migration occurs when the preferred food of alder or birch seed fails. This species will form large flocks outside the breeding season, often mixed with redpolls.
It is a bird that does not remain for long in one area but which varies the areas it used for breeding, feeding, over-wintering from one year to the next.
They are very active and restless birds. They are also very social, forming small cohesive flocks especially in autumn and winter. They are fairly trusting of humans, it being possible to observe them from a short distance. During the breeding season, however, they are much more timid, solitary and difficult to observe.
Population:
UK breeding:
410,000 pairs
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.
This little guy was one of an unusually tolerant flock of eight little beauties.
We had listened for some time to the gentle sound of their named behaviour as they sifted for food along the shore line.
