REPORT ON BIRDS FROM THE NETHERLANDS 
RECEIVED FROM 1 SEPTEMBER 1908 TILL 
1 SEPTEMBER 1909 
BY 
Dr. E. D. VAN OORT. 
(With plate 6). 
In my paper on the Avifauna of the Netherlands, which 
I published in the preceding volume of this periodical, I 
gave a list of all the species observed in our country and 
an account of the most interesting specimens in the col- 
lection of our Museum, with the number of the specimens 
of each species received during the last years. In those 
four years, from 1 September 1904 till 1 September 1908, 
the collection of indigenous birds has been enlarged with 
about 1900 skins, by donation as well as by purchase. 
In the academical year from 1 September 1908 till 1 Sep- 
tember 1909 this collection has been augmented again with 
about 675 skins, among which are three specimens belong- 
ing to two species, Megalestris skua and Serinus serinus, 
which were not represented in our collection of native 
birds. Our collection of indigenous birds becomes by little 
and little the standard-collection for the study of the 
avifauna of the Netherlands; it is at present by far the 
largest and the most complete collection in our country, 
though, as shown in my list of the Netherland birds, 
still some rare examples are desiderata to us. Yet, many 
species are still insufficiently represented and more mate- 
rial, especially that, collected during the breedingperiod,
