>> Hello all,
>>
>> Referring to the foraging techniques of Welcome Swallows, HANZAB says:
>> "Forage aerially, taking prey by sallying or screening..."
>>
>> I can't find the term "screening" in the glossary, and none of the
>> dictionary definitions seem to fit.
>>
>> Can someone explain what "screening" means in this context?
>>
>> Thanks,
