In animal groups where specific individuals disproportionately influence collective decisions, the whole group’s performance may suffer if these individuals have incorrect information. Whether leaders in such situations can be replaced in their roles by better-informed group mates is an essential question in understanding the adaptive consequences of collective decision-making. With pigeons, they used a time-shifting procedure (from an artificially set day-night clock) to manipulate the predictability of directional error in navigational information from established leaders within the swarm hierarchy of carrier pigeons (Columba livia).

More significantly, the pigeon can generalise what it has learned when confronted with new image sets. Like humans, the pigeon's histological (concerning microscopic tissue sections) accuracy was moderately affected by the presence or absence of colour and the degree of image compression. Still, these effects could be improved with further training.

In the previous blog, we discussed several vital glands, including the pituitary gland, the hypothalamus, the thyroid gland and the parathyroid gland. To complete this fascinating topic, we should also highlight the adrenal gland ...
