     The Maritimes Nest Records Scheme (M.N.R.S.) has been operating for twenty years. From 
     
     its modest beginnings in 1960 with seven persons contributing l29 cards, the scheme has 
     
     grown steadily to the present average annual receipt of approximately lhOO cards 
     
     over 80 contributors. The repository now contains in excess of 23,000 record car 3 
     
     for Over 180 species of birds. Provincially, New Brunswick accounts for h9% of the 
     
     Schemes holdings, Nova Scotia for h0% and Prince Edward Island for ll%. 
     
    
   
   
    
     The concept of collecting nesting information, particularly from people who would not 
     
     otherwise publish their data, first began in England in l939 by the British Trust for 
     
     Ornithology. The English idea of a nest records scheme was brought to British Columbia 
     
     in 1955, and now six nesting data collection schemes are operating in Canada (New— 
     
     foundland, Maritimes, Quebec, Prairie, and British Columbia). 
     
    
   
   
    
     The Maritimes Nest Records Scheme was established in 1960 by Tony Erskine of the 
     
     Canadian Wildlife Service at Sackville, New Brunswick. Tony Erskine served as the 
     
     coordinator of the Scheme until l968. The Maritimes Nest Records Scheme moved to 
     
     Saint John, New Brunswick in l969 and was housed at the New Brunswick Museum wher 
     
    

    
     ’ David Christie was its coordinator until 1973. The Scheme returned to Sackville in 
     
     l9Th and continues under the auspices of the Canadian Wildlife Service where Wild— 
     
     life Biologist, Al Smith, serves as its coordinator. 
     
    
   
   
    
     Tony Erskine in his article "A Nest Record Card Program in Canada", published in t 
     
     Canadian Field—Naturalist in 1971, outlines the purpose of a Nest Record Scheme as

     breeding success, (b) nesting biology, and (c) breeding distribution. The 
     
     first objective is of interest to all persons concerned about the continued 
     
     existence of birds, and particularly those responsible for conservation and 
     
     management of bird populations. It is the most critical as well as the most

     in all of these, but especially in the last two objectives.

     Nest record schemes are not and never have been a substitute for detailed 
     
     research, but they can be very helpful. Examination of next record files a 
     
     the start of a study shows quickly whether nests of a given species are easy 
     
     or difficult to find, where studies may begin, and which people may be able to 
     
     give useful advice. Nest records extend the range of special studies by pro- 
     
     vi ing data from areas which the research worker could not visit in the ti 
     
     available. And they save for future studies the by-products of other field 
     
     activities, i.e. observations not bearing on the study in hand, which would 
     
     otherwise pass unrecorded or remain unheeded in a notebook.” 
     
    
   
   
    
     A check on the M.N.R.S. holdings illustratesthe vast amount of data that has accum- 
     
     ulated over the past twenty years. One species, American Robin, has nearly 2500 cards 
     
     on file and two species, Barn Swallow and Common Crackle, have over 1000. There are
