" South " " house 54 " " east " of thick our dam } Mrs. Allen tells me that this colony has regularly built on the premises for the past 15 or 16 years but that it has increased greatly in numbers within the last two years. This is the first season when the birds have attempted to nest under the eaves of the dam shed. Many of the nests were not finished to day I fear that I would miss only just begun. The birds were collecting mud at a puddle of rain water in the road. I hear that there is another large colony breeding under the roof of Mitchell Dam, evidently the birds have increased very considerably in numbers throughout the whole Region since my last visit in 1897. Nearly all the finished nests built on Upton & Errol Dam are of two old-fashioned both without variety. All are well sheltered by broad wings and will withstand, too many of them on chairs? 22
