Treecreeper feeding on Xanthorrhoea nectar

Last weekend (6th August) I visited Booderee National Park, one of the most beautiful and unspoilt parts of the NSW south coast. Long straight flower spikes had shot up like spears from the grass-trees (Xanthorrhoea sp.) and tiny star-like flowers were opening to form a delicate white mantle on their surface. These flowers are highly attractive to nectar-feeding birds and insects; on this occasion it was mostly Yellow-faced Honeyeaters and Silvereyes converging on them. Continue reading

Before the migration: introducing the Yellow-faced Honeyeater

Yellow-faced Honeyeater in Leptospermum

A spectacular annual migration will begin in late March as Yellow-faced Honeyeaters start streaming northward up the coast and tablelands of south-eastern Australia. The waves of travelling birds will continue for 6-8 weeks on suitable fine-weather mornings. Already, observant birders might have noticed small restless groups moving about. Continue reading

The lure of the bottlebrush

When I visited a farm in November to survey the birdlife, I expected a tranquil afternoon in nature. But nature had other ideas.

I walked onto the survey site to be greeted by clamour and movement everywhere. The cackling of dozens of Noisy Friarbirds filled the air with a chaotic din as they chased each other in and out of the bushes. Emerald green Musk Lorikeets scrambled through the foliage, randomly exploding into flight with breakneck speed and a sudden screech. Their young followed, calling wheezily, insistently. Wings fluttered and tails spread in an irresistible signal for their parents to feed them. Continue reading

Function and artistry: an assortment of birds’ nests

Spring is a season of intense activity — not only for our fauna and flora but for me, as this is when I’m busiest leading tours, walks, and carrying out bird surveys. It’s frustrating that the season when I have least time to write is the very time there’s the most to write about. On the plus side, I’m outside seeing it all first hand! I’ll try to make up for my recent lack of posts with plenty of summer offerings, including looks at some of the interesting things I’ve seen during the past three months.

It hasn’t been hard to find birds nesting and feeding young. For many species this continues into the summer months. Australian birds tend to have long nesting seasons (and smaller clutch sizes) compared to cooler-climate northern hemisphere species (see Ford 1989). This allows them to raise two and sometimes more broods, or at least have another try if the first one fails — which happens often. A nest success rate of less than 50% is not uncommon among small birds. This might be due to predation of the eggs or young, parasitism by cuckoos, an unexpected shortage of food, severe weather, bushfire or human interference. It’s amazing small birds manage to reproduce at all when you think of the many dangers they face.

Let’s take a look at some of the nests I’ve found during my travels this season, plus a couple of favourites from last year thrown in. Each is ingenious in its own way.  Continue reading
