(anyone's)wealth+power+(less than required)intelligence = waste of time and energy

If you watch my multi species family for any length, benefits of being more powerful are clear. you get to eat fruits first, you can drink water whenever you want, no one challenges you (well, until you are not threat to their kids - in role of parents one can very well stand up against bigger species too). These things are true 'generally' but effective advantage of such power changes when non routine things like abundance of resources or inter-species interaction gets added. Say, even when there is no scarcity, most powerful may still spend considerable energy in protecting extra food while those in lower ranks manages to just eat and play.

Whatever said, its not easy not to hoard if you have something of value in your hand and cant spend/use it immediately. Our crows too do it regularly. They have a place in a tree trunk where they store extra food. A slight problem with that however is, everyone else too know of their hiding place. When you have a problem and an intelligent creature, you see an attempt to solve it. Few days back I saw a young crow doing exactly the same. hiding extra roti he had at an unlikely place. Very much on the ground. see the video. This one is little longer by my standards. its 1 minute 8 secs, some 11+ MB as uploaded.

I am not very hopeful of this strategy too being successful as many dogs pass by and there are lots of ants also - a big ant nest just nearby. but still, it was nice to see this crow trying out things differently. Even as his efforts to hoard, watch over and then eat those roties in future were certain to go waste and even not required given lack of scarcity, it was at least using his brain and learning new things.

Meanwhile, while I am at crows, here is a small peek into their old behaviour too. Till they realised that it simply wont work, they used to always try to take water home in summer (I used to keep water only in summer then - was quite stupid of me to think they need it only in summer, but learning curve doesn't apply only to crows, it applies to me too.). Its 10 sec. 1+ MB
