Visible tree assessment habitat tree and Picus Sonic Tomography test

Had an interesting day today I have been commissioned by a council in western Sydney to conduct a visual tree assessment from the ground and then assess a defect/hollow about 6 meters above ground visibly using a Elevated work Platform and then to conduct a Picus Sonic Tomography Test. While assessing the tree from the ground I noticed a Cocktail sitting outside of the hollow that I needed to assess (see Photos) using the EWP I gained height so I could start my investigation and noticed the cocky would not leave till I was with a meter of I assume her. Looking inside the hollow I saw at least 1 egg I quickly told the operator to get us away and cancelled the work until after the breeding season had finished. The council were quite grateful on my response :) nice to see native birds breeding in our suburbs
