The Gull and Tern Banding 
Campaign 
HE Inland Bird Banding Association is launching a campaign to 
get as many young gulls and terns banded this year as possible. 
Their secretary is compiling a list of all of the breeding places 
that have been used in the past, that is as many as he can obtain from 
the different persons who have authentic knowledge, and requests 
anyone knowing of any such places to please send in information about 
them. 
The plan is to call for volunteers who will spend their vacations in 
the vicinity of these nesting sites, or those who are willing to take their 
vacation time during the last week of July and the first week of August 
to help out in this interesting cause. In this way we hope to get many 
interesting returns from the birds that are banded. 
Up to date there have been but three returns from all of the water 
birds banded in the world that have crossed the Atlantic Ocean. A Com- 
mon Tern banded on the coast of Maine was found four years later 
floating in the delta of the Niger River, British West Africa. Two 
Black-headed Gulls banded at the German Station of Rositten on the 
Baltic Sea, were recovered from the island of Barbados and Bay Cam- 
peche, near Vera Cruz, Mexico. Then we have one return of a Caspian 
Tern banded by Mr. W. S. McCrea, of Chicago, at the Beaver Islands 
on July 26, 1923; it was killed on November 25, 1923, in the vicinity of 
Bocas de Ceniza, mouth of the Magdalena River, Republic of Colombia. 
This is the only report from the Great Lakes district to South America, 
and it is the reason that the Inland Association is so anxious to have our 
long distance flying birds banded so that we may find to what points of 
South America they travel during their winter migration. 
In the attempts to band these birds, one of the interesting questions 
that are developed is, where do the gulls sleep at night? There have 
been a number of trips made at Waukegan and at Milwaukee for in- 
vestigation. One evening when there was a very strong wind from the 
east of Lake Michigan, the waves rolling very high, and the spray going 
completely over the lighthouse on the outer breakwater at Waukegan, 
it was apparent that no bird could sleep on the surface of the lake that 
night. We thought it would be an ideal time to find out where the gulls 
would sleep. A careful count, on the afternoon of the same day, showed 
that there were over fifteen hundred gulls about the harbor, and for 
making this observation, a careful watch was kept from a freight car 
on the outer part of the Waukegan harbor. With binoculars, one could 
have a perfect view from this car of the inner basin of the harbor, also
