Babysitting elephants: Let the baby boom commence
However, I’ve been so busy over the past few weeks that October has crept up on me unawares. This morning I decided I would cut my field time a little short to give me chance to come back to camp and catch up on all the office work, including writing this post.
Well, it’s 3pm and I’ve been back in camp about 20 minutes, which tells you how successful that plan was. It was worth it though because… …Our first baby elephant of the season has been born – and it’s a girl! One of the lodge drivers stopped us this morning, saying he’d seen a female with a tiny newborn calf. He showed us a picture, and we immediately recognised Qumquat, matriarch of the QB family.
This is only the second birth in 2011 so we decided to head over, and check out how they were doing. It’s important for our long-term records to determine the sex of the calf as soon as we can, especially as this is a family that sometimes spends long periods outside the Park. We found them without too much difficulty, and they were a little wary of us.
This isn’t surprising as we don’t see them very often, and we don’t know how many negative encounters they have with humans outside the Park. The family stayed closely bunched in a defensive formation around Qumquat, and in fact her calf is so tiny we had to wait a while to get a look at her. Elephants are, unsurprisingly, very protective of small calves, and the whole family gets involved in births. Females are very interested in calves and this is true of any female who doesn’t have a calf of her own, and especially of young females who haven’t yet reproduced themselves.
These young females, who we call “allomothers”, provide a kind of babysitting service, helping to guard and guide young calves. They’re important at all stages of calf development – from the tiny newborn wobbly stage, through the start of their exploration and learning, up to the “adventurous-and-bound-to-get-into-trouble” stage. AERP research has shown that allomothers increase the likelihood of calf survival, presumably because it allows the mother to feed uninterrupted for longer periods and therefore maintain her milk production more effectively.
There is also cooperative defence against predators such as lions and hyenas which target small calves. The arrival of a new calf changes the dynamics of the entire family, especially when there are no other small calves present. Qumquat’s daughters stuck close by her, flanking the calf and guiding her with their trunks, and Qumquat often had her tail on her little daughter’s head when the calf followed behind. All this reassurance is very important for young calves.
Whilst we were watching Qumquat and her family, the KA family approached and were very interested in the new arrival. The QBs immediately formed a defensive bunch around the baby, and Qumquat threatened the KAs. New calves provoke intense interest, and sometimes intense interactions. Over the course of the AERP study, we have even witnessed kidnapping of small calves, usually as a way for a family to prove dominance over another.
Once we even documented the coercion of a new mother to leave her family and join another. This happened after a severe drought, similar to 2009, so who knows what will happen this time around? Since so many young calves died in the 2009 drought, most females are now heavily pregnant. Qumquat is the first to give birth in our anticipated “baby boom” but in total, we expect over a hundred calves to be born. This will change everything for the families and we will be able to observe a lot of behaviour that will give insights into the social relationships females currently maintain.
This will help us assess how things have changed for the elephants after losing their old experienced leaders in the drought. On the way back from seeing Qumquat, I stopped at an unusual grouping of elephants at the edge of the palm woodlands close to the Research Camp. In fact, it was so unusual it took me quite a lot longer than normal to identify the elephants present, and it was only when I saw Anghared with a distinctive bump on her side that I realised that part of the AA family were in a place I’m not used to seeing them.
Ava, Anghared’s twelve-year old sister was allomothering a small calf, which I judged to have been born in 2010. I puzzled over who it could be, and then realised it was Anywn’s daughter, from the AC family. She is a particularly feisty calf and soon came to “charge” the vehicle. The AA and AC families were spending time together for the first time in a while, and it soon became clear that Ava and her eight-year-old niece Alfre were having a wonderful time allomothering Anywn’s calf, who basked in the attention.
They played with her and guarded her and were having so much fun that they didn’t notice when the AA females started to move away, heading to the swamp. As Ava and Afre made to follow, the calf ran after them and enticed them to play further. She has no females to babysit her in her own family, and she obviously wasn’t ready for the fun to end. In the end, the AAs stayed with the ACs for another hour, and Ava and Alfre spent more time with the ACs than they did close to their own family members.
Eventually, the AA females called them and, like children unwilling to leave the playground, they trailed along behind, almost dragging their feet with reluctance. It won’t be long before Ava and Alfre have calves in their own family to look after – Amelia, Ann and Anghared are all pregnant. Anghared is particularly big and heavy-looking now, and may only have a month or so to go before she gives birth. Let the baby boom commence…
