the stem, generally choosing the most prominent stalk, as if for a 
look-out station : on the least alarm it instantly disappears in the 
dense cover. So far, I have never succeeded in obtaining an 
example, or finding it when shot at. 
The Blackcap ( Sylvia atricapilla ) is always a rare visitant in 
the northern division of the county. Since 1872 I have once 
only met with it as a probable ncstcr. It occurs in the 
spring as a migrant through the district. A gradually increasing 
species is the Garden- Warbler (S. salicariaj, so common in every 
likely locality, that it may be styled par excellence the warbler of 
Lincolnshire. The Lesser Whitethroat ( S. currucaj, although 
common in the best-wooded parts of the county, may perhaps be 
considered more as a migrant, passing through our north-east 
district both in the spring and autumn, and not, as a rule, remain- 
ing to nest in any numbers. 
I have mot with at least one example of the White-headed or 
Scandinavian form of the Long-tailed Titmouse (Acreihila cuudatn) 
in North-East Lincolnshire. I may add that examples in Mr. Gatke’s 
collection in Heligoland belong to this variety. The Marsh Tit 
(Pants palustris ) is now much more commonly met with than 
was formerly the case even a few years since. The often large 
increase to the ranks of the pretty Blue Titmouse (P. ccnruleus) 
which I have noticed in the Autumn, may be due to immigrants. 
In the present autumn (1878), this increase has been especially 
marked. After the gale on the night of October 30th I noticed a 
considerable increase, amounting to small Hocks, in the hedgerows 
and gardens, and a friend observed the same phenomena in the 
neighbouring parish. Subsequently Mr. Gatkc informed me of 
the immense flights of Pants major and ccerulevs which in the 
same autumn passed across Heligoland. 
The Bock Pipit (An thus obscurus) is in the autumn a very 
regular visitant to our sea marshes and the coast line. I now 
never fail to meet with them. It is very probable that some of 
the examples seen at this season are wanderers from the North of 
Europe, and may prove the A nth us rupestris of Nilsson, the 
Scandinavian form of our English bird. 
Previous to 1872 I had not met with the Woodlark (Alaurla 
arhorea) in North Lincolnshire; since this year I have twice seen 
it, once as an autumn migrant, and again in the summer of 1873,
