 sacher, concerning tliem, that they were found, as above, near Bruck on the 

 Mur, being the tirst nest and eggs obtained in Styria, by an agent of Dr. Fiister. 

 The nestv^as very thick and solid, built of larch-twigs and bast, and having a 

 wide and deep cup lined with hair. This e^g is very similar to those of the 

 Bornholm nest (§ 2594), and not long after it came into my possession

[1855-6.] ''This is the most difficult egg to get, even wlieve the 

 bird is common. Hence it is almost unknown^ and is one of the 

 principal desiderata to continental collections. It is even ranked 

 with the Waxwing in the eagerness with which it is wished for. The 

 bird breeds whilst everything is still covered with the winter^s snow, 

 and is extremely cautious not to betray its nest. Mr. Wolley 

 obtained three injured eggs in 1854, but perfect ones in 1855." 



[1856-7.] " Common as the bird is, and obtrusive as its habits 

 for three parts of the year are, its eggs are perhaps the most difficult 

 to procure of any. Before winter has shewn a sign of departing, it
