The Ninety-first Stated Meeting of the American Ornithologists' Union was held 8-12 October 1973 at Provincetown, on Cape Cod, Massachusetts, under the sponsorship of the Nuttall Ornithological Club, which was celebrating its centennial year. Business, technical, and social sessions were held in the Provincetown Inn. Field trips were taken to various localities on Cape Cod.

The longevity record for a 36-year-old Herring Gull, Larus argentatus (Pettingill 1967, Auk 84: 123), is erroneous. Herring Gull with band number A-676871, the basis of the record, was found dead on 20 June 1966 on the shore of Little Traverse Bay near Petoskey, Michigan, and reported to the Bird Banding Laboratory. The laboratory then mistakenly advised Pettingill that this gull was banded by him

White Leghorn hens were maintained on diets containing 0, 4, 12 or 36 p.p.m. Hg as HgCl2 from hatching in an effort to confirm (with a second species) our previously reported effects on Japanese quail reproduction. In the quail study both onset of laying and rate of egg production were accelerated by 16 and 32 p.p.m. Hg as HgCl2, but ferti ity was depressed. After 1 year on diets containing HgCl

The Breeding Bird Survey has been monitoring bird population changes in the U.S.A. and Canada since 1966. Each cooperator makes 50 3-minute stops at 0.8-km intervals along randomly selected roadside routes in 4 to 4 1/2 hours on one morning in June of each year. Data from the 1500 to 1600 routes are entered on magnetic tape, edited for accuracy, and then used for statistical analysis of population

Salmonellosis caused by Salmonella typhimurium was one of several factors responsible for losses among young herons being held at the Patuxent Wildlife Research Center. The infection was demonstrated in five black-crowned night herons (Nycticorax nycticorax), three common egrets (Casmerodius albus), two little blue herons (Florida caerulea), one cattle egret (Bubulcus ibis), one snowy egret (Leuco

Ability to establish and maintain self-sustaining breeding colonies of captive Red-winged Blackbirds (Agelaius phoeniceus) would facilitate long-term studies designed to develop methods for alleviating blackbird depredations as well as provide basic life history data. To be most useful, the colonies should be established in pens near laboratory facilities; this frequently involves putting colonies

Two barred doves found in the south Kona district of the island of Hawaii were diagnosed as having trichomoniasis on the basis of gross and microscopic lesions. This brings the confirmed list of columbid species susceptible to natural trichomoniasis to four and is the first report of the disease from columbids in the Hawaiian Islands.
