First, some background information on the Yellow-billed Kite.
It is treated at the moment as the same species as Black Kite under the Black Kite name. In other words, there is only one Kite and that is Black Kite. In saying all this, not all the birding bodies have adapted to this yet and even SABAP2 treats them as separate species with Yellow-billed Kite as the more common bird.
Although it is believed that some Black Kites overwinter in our region it has not yet been proved.
From previous years' SABN records I can point out that these birds were seen very early in June:2010
Whilst driving over the Injambili River between Umzumbe and Pumula this morning, July 8, I saw a YBK flying inland. I know this could be an over wintering bird but with what is happening with the weather at the moment who knows. Weavers are in full breeding plumage and busy building nests, Hadeda's are also building nests, I have had immature mannikin's (all 3 species) coming to the feeders since march. Some Flat Crown's are full of new leafs while others are still loosing theirs.2009
This morning (9 July) at 07.10hr. a yellow billed kite flew low over my flat (off South Ridge Rd. near Tollgate Bridge, Durban.) It seemed to look me in the eye and say "Hi- I'm back!" Margie Hoile told me that she saw a YBK on Tuesday 7 July at 4pm over the University sports grounds.Possibly the same bird. I'm just wondering if this is an over-wintering YBK or an early arrival.
I also saw two YBK's on Wednesday, one near Bayhead and one on the Bluff.2008
Saw my first YBK on the Bluff on Monday afternoon (21st), my earliest
Also had an amazing sight driving home yeasterday with about 100 Great
White Pelicans soaring in a single flock over Umgeni Road on route to
Northern Stinks. There are normally about 20 birds in the area so it was
great to see so many at once.
Just a quick note to say I have just seen our first YBK in Highflats today 30th July.
And then a very interesting reply from Barry Porter.
Reports that odd YBK's have been sighted on the KZN South Coast haveScientifically recorded.
filtered through to me during both June and July this year(2007) . They come
from very reliable sources.
Makes me speculate that they are stray over-wintering individuals, and are
unlikely to be very early migrants.
More enlightened comments are welcome.
If you look at records on SABAP2 you will also notice that there are records on Yellow-billed Kite which shows sightings nicely throughout winter:http://sabap2.adu.org.za/species_maps.php?Spp=129
