110 THE BIRDS OF NORTHAMPTONSHIRE 



Mr. T. W. Fitzwilliam, and Colonel C. I. Strong, of 

 Thorpe Hall, near Peterborough. There has for 

 many years existed a tradition that the Herons first 

 nested at Milton in the year that Sir Robert Heron 

 was first elected to Parliament as Member for Peter- 

 borough, in reply to my enquiries into the authen- 

 ticity of this story, both Lady Lyveden and Lord 

 Fitzwilliam informed me that they have reasons for 

 believing that it is perfectly true, and that the year 

 of Sir Robert's return for Peterborough was 1819 ; in

 Lord Fitzwilliam, who told me that he was informed 

 that there were then " as many as 160 nests, probably 

 not all occupied." Another Heronry formerly existed 

 in our county on the property of the late Mr. Thomas 

 Tryon, of Bulwick, whose son, Mr. Richard Tryon, 

 tells me that here again the Herons shifted their 

 quarters from a covert known as the Lodge Coppice, 

 in the parish of Harringworth, to Mavis Wood, in the
