Common Tailorbird’s Nest

“Tailorbirds get their name from the way their nests are constructed. Nests are built with leaves that are pierced and stitched together with spider’s web or plant fibre. The leaves are pulled together and stitched to form sort of a cradle where grass or other materials are placed within to construct the actual nest.

“It was end 2012, when I stumbled upon a Common Tailorbird (Orthotomus sutorius) in the act of constructing a nest. Of all places, it had chosen to build its nest in a park around the Civil District area. I first saw this tailorbird collecting twigs. It was cautiously looking around before returning to its half-built nest that was situated almost at the top of a row of shrubs that was just a metre in height and around half a metre from the edge of a paved walkway. To my surprise, in addition to the natural nesting materials, this nest was filled with tissue papers! The loose materials in the nest meant that this was at an early stage of nest building. The bird was observed entering the nest to place nesting materials.

“In order not to attract undue attention and unwittingly exposing the nest, I did not stay at the same spot. I loitered around to take in other sights. It was then that I discovered another 2 additional nests that were along the same row of shrubs. Both were less than 10 metres away from the first. Tissues could also be seen in the second nest. [The image above shows the bird collecting tissue paper.] The third nest seemed to be fully completed using normal natural materials, but its internal content were well concealed and cannot be ascertained.

“Observing discreetly from different spots, I can only see one tailorbird, probably a female, judging from a lack of longer central tail feathers. Although this bird was focused on constructing the first nest, it seemed to also visit the second nest. For unknown reasons, its flank feathers were fluffed and displayed before it flew into the crown of a nearby tree. I left for an appointment with the intention to check on the nests the following week. As fate would have it, it rained heavily and I was unable to visit the site until early January 2013.

I had prepared for the worst as there were heavy rain storms with strong winds the last few days before my visit. Alas! It seemed that nature or the adverse weather was not the only threat. There were signs that the shrubs have been trimmed, probably by National Park’s contractor. It was likely the work of Homo sapiens that took away all the hard work of this Common Tailorbird. Sadly, this is another record of failed nesting.

    Thanks Wai Chong. Appreciate the excellent images and commentary. Having watched a few nests being constructed I agree that often it is one bird doing it (or at least a female staring off the process).

    Reading Gerald Durrell about tailor-bird nest building, he says ” no-one knows how the thread is made” . Your article says it is plant fibre or spider silk, but how does the bird make this into a thread it can sew with?

      “…female selects suitable leaves, pierces a series of holes around perimeter of each leaf, and finally threads strands of fibres through holes, pulling fibres through quite tightly (but ends are unknotted); …”
