2016- Week 52
- (Added 11. Dec. 2016 - 11:00)

We seem to have got to week 52 before the end of the year… Oh well, makes a good reason to wish everyone a Happy Christmas and all the best for the New Year. I’ll be back in 2017.

To finish the year we have a very interesting montage that demonstrates group vigilance in ostrich. These images are all taken 2-3 seconds apart. Note how the number of birds keeping lookout changes from frame to frame. It also appears that the males are more often vigilant than the females, although this is hardly a significant number of observations!

The is MY bit of mud…

2016- Week 50

While we cannot tell from the image whether this sub-adult male lion is actually roaring (rather than making a Flehman response to a female scent) it would be odd to hear him make much sound at all. Sub-adult males tend to very quiet and only start loud roaring when they feel they can start to challenge for a territory. This usually happens after they have dispersed. Maybe he is roaring in very quiet ‘test’ mode…

2016- Week 49

I mentioned previously how some of the larger eagles are quite happy to occupy a space at the waterhole regardless of the number of other animals. This African hawk eagle sat in the water for more than 40 minutes while various other species milled around. He or she even allowed gemsbok (known for their intolerance of others at water) to approach within a meter or so. African hawk eagles are especially ‘sticky’, tawny eagles to a lesser extent, while Verraux’s eagles will fly away if any mammal gets within about 5 meters.
