Miihlbach, where lie has seeu them, and where he tried to 

 take the nest m the hollow oak trees in which they breed every 

 year. Bieltz gives the Stadtwald, near Hermannstadt, and 

 the rocks in the Rothenthurm Pass (where he says it probably 

 breeds) as localities. Herr Csato says that it is rare in the 

 Strell valley, appearing in spring and leaving in autumn. It 

 is the first migratory bird to leave the country. 



■^11. Falco tinnunculus, L. Vercse (Tower-Hawk). 



Very common everywhere : does not generally remain over 

 the winter, but arrives in March and April, and leaves in the 

 late autumn. It has, however, been known to stay, as Herr 

 Otto frequently saw about ten pairs at Klausenburg in the 

 cold December of 1868, a winter in which field-mice were 

 unusually abundant. 



12. Elanus c\eruleus (Desf.). 



We insert this on the authority of Graf Lazar {'' Kurtze 

 Beitrage zur Ornithologie Siebenbiirgens^^), who states that 

 one was killed at Benczencz, where he lived. 



■^13. Pandionhaliaetus (L.). Halcisz Sas {Fisher l^ngle) . 



Generally distributed, but not common. We saw a couple 

 by a lake near Zali about the middle of May. Herr Otto, 

 though he had seen them both at Zah and at Gyeke-Czeg, 

 had not, in 1872, discovered where they breed. They may 

 also be met with in summer on the Strell. 



14. Pernis apivorus (L.). 



Rare. It has been found breeding in a wood near Lesch- 

 kirch and at Nagy-Enyed. There is a specimen in the Klaus- 

 enburg Museum which was killed at Gyorgyfalva. 



^15. CiRCAETusGALLicus(Gm.). Kifft/o Sus {Snokc-l^agle) . 



We shot a fine male specimen in a wood at Szent Mihaly, 

 near Klausenburg. The eyes of this specimen were bright 

 lemon-yellow, and the same colour as the cere. Authorities 

 are agreed as to its breeding in the country, and state that 

 it is not uncommon. Known localities are the Biik (beech) 

 wood near Klausenburg and woods near Piski ; and Herr Buda 

 has shot several at Ilatzeg, and seen them often.
