close sitter. When the eggs are f<r hard-set ” such is doubtless 
the case, but a series of observations made during some 
twenty years shew that, even when there is a full clutch of 
fresh eggs, it is seldom possible to approach quietly enough 
to find the bird on her nest. She usually leaves it “ at long 
range.” 
Again, the Grasshopper-Warbler is even now plentiful in 
many years in the Cambridgeshire Fens, and builds there on 
the ground among the sedges, more commonly than in the 
grass. A single specimen of the Reed-Warbler has now 
been taken at an Irish lighthouse, and Evans has found a 
Marsh-'Warbler’s nest in a tuft of Willow Herb at Horsey in 
Norfolk. 
47. Loudon on the Birds of the Baltic Provinces. 
[Vorlaufiges Verzeichnis der Vogel der russisclien Ostprovinzen

We are all acquainted, more or less, with the excellent work 
Baron Loudon is doing on the Birds of the three Baltic 
provinces of Russia. We have now received a copy of what 
appears to be a kind of summary of his work and a revised 
list of the species as yet recognised as occurring in this 
interesting district. 
After a preface, which deals with previous authorities on 
the subject, follows the list of the birds of the three 
Provinces in a tabular form, which contains the names of 
300 species. It also states in which of the three Provinces 
the species occurs, and whether it is a resident or a more or 
less scarce visitor. Altogether we find enumerated :— 
Residents . 54 
Summer Visitors . 143 
Passengers . 40 
Winter Visitors . 16 
Accidental Visitors . 47 
300 
We think that students of the Palsearctic Avifauna will 
find this a very useful and instructive list.
