This is plain wrong and is NOT how air flows through the avian respiratory system.
There is no difference between a 1st and 2nd breathing cycle.
During inhalation air splits at the end of the mesobronchus and ~1/2 enters the posterior air sacs whilst the rest passes through the lungs and into the anterior air sacs.
During exhalation air from the posterior air sacs pass through the lungs and exits via the trachea whilst air from the anterior air sacs exit directly via the trachea.
Thanks so much! This totally saved my life. We had to do a project where we designed an animal, and I wanted to do a bird, and I finally found something that easily explains respiration!
I actually really enjoyed this. It did a better job explaining than my book as well; it took me a while to understand the word "cappilary" :) thanks though!!
Thank you very much for helping me get a higher mark on my final tomorrow.

google for Airflow and respired gases within the lung-air-sac system of birds to get a paper by J.H Brackenbury
Or Google for bird lung and select the people.eku.edu/ritchisong/birdrespiration page. Its usually the first hit.

Thanks. I was just watching a documentary on birds and I missed what they said on respiration. This explains what I think I missed perfectly!

Hey thanks for the video, about 30 mins revision from a textbook compressed down into a 2 minute video saves a hell of a lot of revision, thanks!
