Dear David,

I am glad to present you copies of my two articles, which was published in the following scientific magazines: “Proceedings of The Royal Society”, vol.274, no. 1624.pp.2373-2508, 7 Oct 2007 &  “International Society for Behavioral Ecology Advance Access”, Dec 6, 2007.

In these articles I described how we have been using your excellent Brooders for raising, hand feeding and photographing the House Sparrow (Passer domesticus) – the subject of my recherch: “The adaptive value of parental responsiveness to nestling begging” and “Can hungry nestling be trained to reduce their begging?”.

The purchasing of four high quality Brooders – adjustable exactly to my needs – allowed me to conduct along the years complicated experiments with utmost convenience and without any problems.

I thank you also for your support and for all other advice; there is no substitute for your creativity in finding technical solutions and I have no doubt, what so ever, that all other appliances will be acquired from your company.

With much appreciation,
