Technically, sunbirds shouldn't be considered LBJs, but female sunbirds ... :roll: Is there any way of telling which these two might be? They were seen at Bontebok NP on 3 October 2009 and there weren't any males about to make an ID easier ... :hmz: I'd think that they are not malachite females, but could be either lesser or greater doublecollared females ... and from the pix in my Newmans there doesn't seem to be any way of distinguishing between these two :wall: :wall:

Hi Arks,

Yes, female sunbirds can indeed pose a challenge right up there with the toughest of LBJ's. Some of them have markings on the underparts and eyebrows which makes ID a bit easier but then there are also those of which the only noticeable feature is that they have no noticeable features. Your bird is one of those :lol:

When it comes to these sunbirds the size of the bill is often the most useful field characteristic and by the looks of your bird I wouldn't say that it is long enough for Greater Double-Collared Sunbird. I'd agree with you that the bird is not a female Malachite either as I can't discern any yellow colouration or bright enough white outer tail feathers.

So I would think that both of your birds are female Southern Double-Collared Sunbird.

I agree, bill length does seem to fit Southern Double Collared Sunbird best! :thumbs_up:

Thanks for the good laugh here, deefstes, and all the other interesting info and insight on these perplexing females :thumbs_up:

And thanks to RJ for seconding the ID — altho I'm still using the old/alernative name of lesser doublecollared sunbird. As only a part-time RSA birder, it will take me time to get familiar with all these new names :wall: :whistle:

Good morning everybody. I hope you all had a good weekend.

Over this weekend, I captured the following in my gardedn and have a couple of questions.
The first 2 I have IDed as a male and female Lesser Collared Sunbird, however, none of my books mention the apparent yellow marking on the male - am I wrong with my ID or is this an odd one?

I was also so happy to see my first "static" Malachite Kingfisher at Intaka Island, now if only I can keep the camera as static to get an in-focus shot it would be great. :tongue:

Correct with the ID's :thumbs_up:

The yellow tufts on either side of the breast band occur in the males in full breeding plumage.

Correct. Lesser Double-collared is also known as Southern Double-collared as there are more 'splits' than in a piece of rotten wood. Most of em sport the yellow pectoral patch but beware accidental pollen smears too.
Good luck with the Malachite photograph, One day one WILL sit still long enough with no branches or shadows in the way etc., and your focus and exposure will be just right and the battery charged. :cam:

Anyone know what the yellow pectoral tufts are about?

I was going to post a pic with a bird with them, but Nannie has done so.

As far as I know it is used for breeding display.

All our sunbirds possess yellow pectoral tufts and display them to varying degrees, often during courtship, but also when they are involved in territorial disputes. However, recent experimental evidence has shown that such signals may not always be sexual in nature or related to male on male interaction. Some sunbirds have been observed to display their tufts at night while sleeping and the thinking is that it may serve as a deterrent against some predators.

The tufts often also show well when the birds are preening, fluffed up in cold weather or when bathing, but these “displays” are unintentional.

:thumbs_up: Thanks Oom & Joh!

Will post my wife's pic later. It was rather chilly at BNP, but most of the SDCS we saw were not displaying yellow.
