Dear Birders,

I have noticed a few messages recently that point out a few errors in HANZAB. Naturally, a production of this magnitude will always have the odd error, but overall I think it?s a fantastic set of books. However, I do have another error to add that I discovered in the data collection stage of my honours thesis. In the section dealing with breeding of the Gibberbird (Ashbyia lovensis) on page 1257, three egg sizes are quoted from Waite 1917 and White 1917. The quoted sizes are approximately 27.8 x 26.6mm. A bird of approximately twice the mass of a chat would normally lay eggs of this size, and as the Gibberbird is not related to the Kiwi, this is obviously an error. I am unable to provide referenced egg dimensions for Gibberbird but did measure a number at the Melbourne Museum and the mean average I calculated was 20 x 15 mm.

On a different note, mum and I were at Werribee Treatment Plant two days ago and was pleased to see an Arctic Jaeger (S. parasiticus) pursuing Silver Gulls. Now we only have to find those Freckled duck that Shirley keeps seeing and we can never find! Well, you win some, you lose others!

Successful birding,
