.bag german . finally Jep Beg c erm&n spoke aoout the Black Tern but again 
she ad ed little to whet w as at id last time. The stooping asture, 
the anr logue of the BcugestelLung, looks rather li .e whet is an 
intentejt^on to scrape in the Arctic, The black tern never scaapes 
but in two situations where the Arctic scrapes the black tern adopts 
a posture which is not distingue ihaole from stooping. These situations 
are immediately following the arrival of a femtle, as part 01 the greet in 
and in order to attract the young, irossioly the Bruges tel lung oi' 
the Blf ck tern is oeriveo. from scraping, which would imply that it 
must be also in the other sop. too. There is certainly so me 
kind of cl use connection between these activities in the xrct-c 
but there are aiflerenc es too which are uiii-icult to explain. 
This possibility would throw light on the uniuentii ieu display oi 
the Sandwich tern of which i he vs made a picture in which the birds 
stand heac. to head, i'or the one thing which is certain about this 
posture,* s ft x- as I was able to discover, was that it ws- often 
followed by scraping. Thy an in t Get ion move .cnt oi scraping 
shoulc ,ock like that in the Sandwich torn is of course stil unexplained

important point v.hich is unexplained about this posture ana that is 
why it should occur in such a widespread way in the keritl ais;lay.
