There are many kites made to resemble birds, and this, from Premier Kites, is one of the larger ones at over 9ft wingspan.  It is very stylised rather than trying to imitate a real bird, but none the worse for that.  It is easy to assemble, and flies well in quite a wide range of conditions.  It has a tunnel keel, which is supposed to help stabilise it, and it seems to do a good job.  The higher this kite goes, the happier it seems to be.  It is quite strongly made of ripstop nylon with fibreglass spars and available in several colours.  The list price (2011) is $87.50; I notice they are currently on special at Picture Pretty Kites for $53 – a real bargain.
