Hello friends, back to Ethiopia.
What are these crocodiles talking about?
This photo is taken at Lake Chamo near Arba Minch from our boat which was a little bit larger than the crocodiles, about 8 metre!

DIET:
Although the juveniles are generally restricted to eating small aquatic invertebrates and insects, they soon move onto larger vertebrates (fish, amphibians and reptiles). Adults, however, can potentially take a wide range of large vertebrates, including antelope, buffalo, young hippos, and large cats. Fish and smaller vertebrates often form the greatest part of their diet, however. As with C. porosus, they have a reputation as being man-eaters, although probably kill more people than all other crocodilian species combined. Along with hippos and lions, crocodiles account for perhaps a few hundred deaths and disappearances each year, although exact figures are very hard to verify. Nile crocodiles will also often scavenge from carcasses, together with a number of other animals, all of which seem to tolerate each others' presence. They have a rather well-known relationship with several species of birds (e.g. spur-wing plover, called "trochilus" by Herodotus) which are reputed to pick pieces of meat from between the teeth of the crocodiles as they gape - the birds gain a meal, the crocodiles have their teeth cleaned of scraps they could not eat themselves. Whether such a mutual relationship actually exists is hard to determine from the literature and anecdotal reports, but seems more likely to be opportunistic rather than symbiotic.

Several prey animals have been found wedged under submerged branches and stones, leading to reports that the crocodiles store unwanted prey here until a later date. Some claim that it is necessary for the prey to decompose before the crocodiles are able to tear portions of flesh off, but this is unlikely to be true. The flesh may become softer if the prey remains in water after death, but crocodiles will certainly avoid rotting meat. When feeding, a number of individuals will hold onto a carcass with their powerful jaws whilst twisting their bodies. The anchorage provided by the other individuals allows large chunks to be torn off for easier swallowing. A few lone individuals have been reported to wedge prey between branches in order to provide the anchorage necessary for such actions to be effective, which could even be claimed to be a form of primitive tool use.

Other cooperative feeding behaviour has been reported, such as the action of many animals to cordon off an area of water to concentrate fish within. A hierarchy of feeding order is often observed in such situations, with more dominant animals feeding first. Groups of crocodiles will often move onto land to scavenge from kills made up to several hundred metres from the water. Adults have also been observed fishing using their bodies and tails to corral the fish towards the bank where they are concentrated and picked up with a sideways snatch of the jaws. Social behaviour in Nile crocodiles is often underestimated, although there are many aspects still poorly understood.

It has been observed that social status may influence an individual's feeding success, with less dominant animals tending to eat less in situations where they come into frequent social contact with other, more dominant individuals.

BREEDING:
This species digs hole nests up to 50cm deep in sandy banks, several metres from the water. These may be in close proximity to other nests. Timing of nesting behaviour varies with geographic location - it takes place during the dry season in the north, but at the start of the rainy season further south, usually from November through to the end of December. Females reach sexual maturity around 2.6 m, males at around 3.1 m. Females lay around 40 to 60 eggs in the nest, although this number is quite variable between different populations. Females remain near the nest at all times. Incubation time averages 80 to 90 days (ranges from 70 to 100 days), after which females open the nest and carry the juveniles to the water. Both males and females have been reported to assist hatching by gently cracking open eggs between their tongue and upper palate. Hatchlings remain close to the juveniles for up to two years after hatching, often forming a creche with other females. As with many crocodilians, older juveniles tend to stay away from older, more territorial animals.

Despite the vigilance of the female during the incubation period, a high percentage of nests are raided by a variety of animals, from hyaenas and monitor lizards to humans. This predation usually occurs when the female is forced to leave the nest temporarily in order to thermoregulate by cooling off in the water.

Hi Peter,
Great action moment captured and those huge mouths look so scary. But I would have liked to see the entire scene....would have given the shot a different dimension. Anyway, a superb image. Kudos.

Merhaba Değerli Dostum Peter!
Bu ürkütücü hayvanlara bu kadar yaklaşıp, böylesi detaylı foto çekmek gerçekten yürek ister. Kestrel çalışmamı favori fotolarınız arasına almanız büyük onur benim için. Çok teşekkürler.

Hi Peter,

This was a perfect photo op. The trio of crocodiles all with their mouths wide opened is fantastic. Excellent details of their skin, teeth, and all the way down their throats. A great shot and I'm glad they were too busy to bother your boat.

Jane

Hi Peter,
I've seen a few crocodiles in my time,but these ones look like absolute monsters!
That one on the right looks SO fat!
These must have been nearly as big as your 8 metre boat.

An amazing shot.
Cheers & TFS

Hi Peter.
Nice composition with excellent low POV.Good detail and sharp image.I also like the idea of having a BG that is not to much OOF.
TFS Michel

You know what I like best about this one? It was shot at the full 300mm:-) Even when relaxing these creatures look frightening..I suppose in some cultures they carry a different feel, but in my short years in Florida back a long time ago I saw my share...with no camera..Very interesting and unique pose!

Hello Peter !
I don't think I really want to know what they are talking about - better stay away from them ! :-) Their teeth ook really impressive ! It is really a fantastic capture, to have 4 of these dangerous animals, mouth open, on the same picture. Very well done !
Valérie.

Ciao Peter. Chatters among four little friends? Great compo in amazing light. TFS.

Roberto

Hallo Peter,

ja dit soort opnames maak je niet in de Nederlandse natuur.
Mooie compositie en gezichtsveld.
Prima plaat.

Gert

Hello Peter

Have a good night
Jacqueline

Ciao Peter, lovely hungry quartet in nice pose, splendid capture with great sharpness and fine details, very well done, ciao Silvio

Look at those gigantic, cave-like gaping mouths!
This is a very timely action shot you took during your trip to Ethiopia, Peter.
Despite the harsh sun, you have managed a good shot of the congregation of these 'talking' Crocks.
Thanks and regards.

Hello Peter!

Looks very nice, but only in picture :-) I think these reptiles could tear you apart and eat in three seconds or less :-) Anyway - great picture with funny scene. Animals look like old ladies sitting and talking about gossips. Beautifull colour of water BTW. I like it.

Hi Peter.
I hope you was far from these impressive animals. However, close-up is fantastic, with great clean and bright colours, terrific sharpness and details of the FG and cute group of tender :) creatures. I also like impressive BG. Bravo. Perfect, pictorial shot.

Have a nice weekend,

Hi Peter,
Fantastic photo with a great title. :) Probably the crocodiles talked about "let's open our mouth to help Peter in order to make a bombastic shot". :) This image really is. I mean bombastic. And You were brave to close them so much.
Congrats and tfs, regards from Hungary, László

hello Peter,
excellent capture for huge three crocodyles. great timing, POV, focus. nicely composed. thanks for sharing.
sorry for my silence. I have been in field work for a long time and it will finish at the end of summer. Now, I can visit your last post.
best wishes
Ahmet

Un trabajo impresionante Peter, que te pone en escena y te hace soñar con otras tierras. Originalidad ya que despiertas interés incluso sin verse los cuerpos de los reptiles.
Saludos: Josep Ignasi.

very good pose
great details and good sharpness 'the colours are very good
greeting
