Over the wet season two species of mistletoe (Amylotheca subumbellata and Amylotheca dictyophleba) have been flowering and fruiting in the village.

This is a window of seasonal plenty for Mistletoe Birds (Dicaeum hirundinaceum) who live mainly on the mistletoe fruit and repay the favour by spreading the seeds of mistletoe.

The photo here of a female mistletoe bird was taken from the back deck of #56 at the start of the rainforest walk in mid-February. It wasn’t until the photo was uploaded and cropped that it became apparent the shot had captured a gluey seed locked and loaded for dispersal.

Although there are other birds that can spread mistletoe, the mistletoe bird has evolved a highly specialised and efficient method of ensuring future crops of mistletoe berries.

As a parasite, mistletoe seed needs to be placed in a particular way in the (usually) upper branches of the host tree. Mistletoe minimizes opportunistic feeding by less specialist dispersal species by producing few, inconspicuous fruits. The fruit is low in protein and so the mistletoe bird must eat large quantities for reproduction and moulting.

The mistletoe bird has evolved a digestive system that processes the fruit particularly quickly and with little damage to the seed. It takes between four and 25 minutes for the fruit to be processed and ready for “planting”.

The fruit emerges with a sticky coating that requires the bird to employ a special technique to detach it from the anal vent. Mistletoe birds often stand facing the host plant and with a wiping action deposits the fruit in a string along the perch. Seeds that emerge from mistletoe birds are much stickier than those of honeyeaters who also snack on mistletoe fruit. Seeds ejected by honeyeaters fall randomly and often miss the strong bonding to the host tree branch that is essential to keep the mistletoe supplied with a source of fluid as it grows.

Mistletoe birds occur throughout Australia in any habitat where mistletoe occurs. They are the only Australian representative of the flowerpecker family, Dicaeidae, which comprises 50 mistletoe-loving species distributed through tropical southern Asia and Australasia.

The male mistletoe bird is brightly and colourfully feathered while the female has more demure plumage, dark grey above with a white throat, light grey underparts and just a touch of pinkish red under the tail.

Jamie Oliver previously posted a link to a great David Attenborough segment that captured the whole process including a time-lapse of seed germination. That link is here.

In early March a number of mistletoes were flowering nicely in “the cutting” around 21-27 Mt Spec Road.

Nearly six years ago, in a rush of enthusiasm, I published what I hoped would be the first in a monthly series of articles on Paluma Birds. That post featured the Satin Bowerbird. Unfortunately, I never followed up with further articles, despite my feeling that this was a worthwhile project that could be a nice complement to Colwyn Campbell’s very successful Tree of the Month series, which persisted right up to the end of 2021.

I am delighted that the series is now restarting with the able support of Peter Cooke, whose first post features the mistletoe bird. Peter and I have several birds lined up for future months and are confident we will be able to keep the series going at least for this year. However, we would be delighted to receive contributions from other residents. If you have a well-framed, sharp portrait of a local bird that you would like to write about please contact us. We can help you write the text, or contribute some text to go with your picture. In either case, let us know! We are very keen to use photos by residents as our primary source of illustrations for the series. if you realize you have a great shot of one of the birds we feature in a post, and would like to share it, I can include it in a comment on that post after it’s published (unfortunately the system does not allow general users to include photos in the comments section).

I hope you find the series informative and interesting.
