Clever crows and a bossy ibis

Family picnic at Centennial Park, Sydney

Earlier this year we spent just over 4 weeks visiting our son and his family in Sydney. Over recent weeks I’ve shared some of the birding experiences we had while there, and when we weren’t on grandparent duties. On the very last day we had a family picnic at Centennial Park (see photo above). Some of our son’s friends were also present and the weather was brilliant; bright sunshine and just a hint of a breeze.

Over the course of the afternoon I managed quite a nice list of the birds observed in the park, including a few flying overhead. The most prominent in-your-face species were the usual suspects: Noisy Miners, White Ibis and Common Mynas. We had to be on guard all the time and some of our friends’ biscuits were snatched from packets within a metre or two from where we sat.

One species I didn’t expect to join this thieving group was the local crows, or more precisely, Australian Ravens. Now I have known that crows and ravens are sneaky, opportunistic thieves since the days when I grew up on the family farm in the mallee districts of South Australia. The local Little Ravens thought nothing of snatching a few eggs from our laying hens and ducks. On this picnic, however, I saw them in a different light; they are very clever.

In the photo above I’ve captured an Australian Raven “red handed” in the act of stealing some food from someone’s picnic. The bird was clever enough to know what was food, how to get it out of the basket and even  how to open the plastic bag to get at the food. I am not sure what the food is – perhaps some cut up watermelon.

Within a few seconds, the successful heist was noticed by several White Ibis patrolling the picnic area. In the photo above the raven was still in control of the stolen food, but the ibis was about to take over. They are the “bully boys” in this situation, one that is repeated in many picnic grounds throughout eastern Australia.

It wasn’t long before an ibis had taken over eating the human picnic food (see photo above). Within a very short time several other ibises joined in the feast. Even a Rock Dove (feral pigeon) comes over to see if it can get into the act (see above, top left corner of the photo).

The raven wasn’t to be outsmarted, however. It went to another picnic spot nearby, rummaged through the human food delicacies and came up with something edible in a paper bag. To minimise the chances of being noticed and being bullied out of its catch, it flew to a nearby tree. There it was successful in holding the paper bag against the branch, opening it up and getting at the food (see photos below).

Very clever.

Observe the feathers (called hackles) on the throat. This helps identify this bird as an Australian Raven.
