Fat and formation in flight
Article Abstract:
Two research projects have used total power measurements to test two long-standing aerodynamic predictions. One project looked at how power varies with body mass in individual birds, while the other considered the impact of flying in formation on energy usage. It is clear that there is a need for greater knowledge about how flight muscle functions.

Carrying large fuel loads during sustained bird flight is cheaper than expected
Article Abstract:
The doubly labelled water technique was used to assess the total metabolic power input in a red knot flying for six to 10 hours in a wind tunnel. It was established that total metabolic power input rises with fuel load, although proportionally less than the anticipated mechanical power output from the flight muscles.

A fundamental avian wing-stroke provides a new perspective on the evolution of flight
Article Abstract:
Several researches are conducted to explain the fundamental avian wing-stroke that leads to a completely new explanation for the evolution of flight in birds. The incremental adaptive stages of flight evolution are found to be similar to the transitional stages observed in ontogenetic forms.
