Three of the six kangaroos graze beneath a tree.

Recently, I wrote about a new mob of six Eastern Grey Kangaroos which seem to have displaced our usual mob of three.   Unlike the previous mob, they are not on our land all of the time.

Kangaroo Diary

If I see kangaroos of a morning or evening,  I do take at least a couple of photographs to document the days they visit.   They were here:

  • 1 September
  • 9 September
  • 17 and 18 September
  • 25 September
  • 2 October
  • 7 October
  • 14 October (today)

It’s not quite clockwork, but there does seem to be a pattern emerging of approximately a week to ten days between visits.  This suggests they have a regular territorial routine which they follow.

Mob Structure

Today the kangaroos came closer to the house than they have previously done.  I was able to work out the structure of the group.

The dominant male seems tolerant of other, younger, males in the mob.  Usually he sticks pretty close to the dominant female, who is carrying a joey in her pouch, but I’ve also seen him grazing slightly away from the others, as if keeping an eye on them from a distance.  If there is a noise or something that attracts his attention, he will move close to the others and stand up high in a protective manner.

The dominant male and female of the mob. She is carrying a joey almost ready to leave the pouch.

 

Two younger kangaroos seem to be forming a bond.  This is a young male and female, much smaller than the dominant pair.  I’ve seen the dominant male and this younger one grazing side by side without any apparent tension. This younger male seems quite dark compared to other kangaroos, just like the dominant male.  My hunch is that it could be an almost grown joey from a couple of years ago.

This female kangaroo seems quite small. She would reach the shoulder of the adult female. However, you can see the pouch opening. I wonder if she has a tiny joey?

 

The sixth member of the mob is a young, single, male.  While he is tolerated by the others, he is always grazing away from them.  It is almost like he is following them rather than part of their group. However, I haven’t seen any aggression toward him.  It seems he is able to move around with them as long as he knows his place.

Perhaps he is related to the others – possibly last year’s joey? Whatever the case, this young male seems to be slightly away from the others all of the time.

Later on in the week I will post some photographs of the joey, which came out of the pouch for a quick play this morning.
