This nest of the malachite sunbird Nectarinia famosa
can be right in your face and it will still be invisible.
We have two sunbirds on a regular basis in our garden
in the Western Cape. The malachite sunbird with the
male a glittering green all over and the smaller sunbird
Nectarinia violacea (also refered to as Anthobaphes
violacea) where the male has a glittering red/orange
breast. The females of both are little brown jobs.
They love the nectar of the Aloe sp. and also the
Cotyledon sp. I am not an expert in birds feel free
to correct me if I am wrong.

The nest was exactly the height of my face
right above
the path. I do not know if the they
hatched any chicks
but the sunbirds must have spent a lot of time
building the nest without us noticing them.

It is a pity that I do not have a camera with a zoom.
The birds will thinknothing of sitting right next to us
when we are in the garden, but we must not have
anything in our hands. I tried walking with the camera.
Fine, they got used to it, but the moment I lift it in
their direction, they dash away.
There are more
nests in the garden. The juveniles
resemble the females I guess we might have seen
some without realizing they are "our" birds.
All birds
are welcome in the garden and we see
to it that they get some treats and water,
but we are not into birding as such.
--------------- I had to add this September 2009.
I found this little female malachite sunbird nesting
on the other corner of the house.
The height of the nest above the ground is
obvious by the window in the background -
the white is the window pane, not the sky,
with the redish window sill at the bottom.
The nest is slightly larger than a man's fist.
Now that I know about the nest I make a
small detour around the tree, where I would
normally pass directly against that branch.
It obviously did not bother the birds in building
the nest, but I will do my share.
