Figure 143 - April to July guillemot densities from Vantage Point ( VP) counts around the Butt of Lewis. The horizontal axis shows the distance from the VP (in any direction) and the 'depth' axis shows the actual distance from coast. Auk densities in these distance from coast bands from the four aerial survey transects around the Butt of Lewis surveyed between April and July are shown on the right (in blue) for comparison

Figure 144 - April to July razorbill densities from Vantage Point ( VP) counts around the Butt of Lewis. The horizontal axis shows the distance from the VP (in any direction) and the 'depth' axis shows the actual distance from coast. Auk densities in these distance from coast bands from the four aerial survey transects around the Butt of Lewis surveyed between April and July are shown on the right (in blue) for comparison

Figure 145 - April to July black guillemot densities from Vantage Point ( VP) counts around the Butt of Lewis.
