They are capable of flying but aren’t as efficient as other owls.

How did the Atlas get its breeding data?

However, Atlas volunteers were not just collecting breeding evidence in the breeding seasons of 2008 through to 2011; they were also undertaking timed visits to tetrads (2km by 2km squares) and counting all of the birds seen and heard, in a standard one or two-hour period.

How does the Atlas change over time?

The Atlas changes over the period between 1988-91 and 2008-11 represent multiple visits to every 10km square in the country, for both time periods. It’s not possible to maintain this level of coverage on an annual basis so BTO also runs the Breeding Bird Survey (BBS) with our partners, JNCC and RSPB.
