Autumn Movements

We have had poor weather conditions for the last couple of weekends, including being completely rained off last week.

But on April 2nd we had excellent banding conditions and the birds did not disappoint. The large movements of Silvereyes typical of this time of year have started, and these made up the majority of our catch (100 birds, 74 of which were Silvereyes). We controlled one Silvereye from nearby Bold Park, the same bird we controlled in January.
This session also marked a significant milestone where we surpassed a total of 7000 Silvereyes banded over the course of the Herdsman Lake Project.

No waterbirds this week, however we still banded a couple of larger birds in the form of an Australian Raven and an Australian Hobby.

The highlight of the day was a most unexpected Western Spinebill, only the sixth ever banded at Herdsman Lake. It was a young bird and probably just passing through, as we tend to see in species like White-cheeked Honeyeater at Herdsman.

Breaking Records in February

Apologies for the lack of recent posts. Here are the last three weeks of banding at Herdsman!

20 Feb 2016
This weekend was rather slow and we only processed four species during the Saturday morning. Surprise numbers of Striated Pardalotes made up for the low numbers of Silvereyes.

Species - New (retrap)
Pacific Black Duck - 1 (1)
Silvereye - 6
Striated Pardalote - 12
Willie Wagtail - 2 (1)
Total - 21 (2) = 23

This Saturday made for an exciting February banding session. We caught good numbers of Silvereyes including 10 recaptures. Many of the Silvereyes first caught in December/January in juvenile plumage are now moulting or have finished moulting into adult dress and are difficult to distinguish from older birds.
A smattering of Australian Reed-warblers was a welcome addition, as was an Inland Thornbill, only the third ever for the Herdsman project.

On another note, for the first time ever the catch exceeded 1000 birds before March (our 'banding year' starts in July and runs until the end of the following June). The total came to 1028 birds on our last banding session for February.

Species - New (retrap)
Australian Reed-warbler - 6
Brown Honeyeater - 1
Inland Thornbill - 1
Pacific Black Duck - 1
Rufous Whistler - 3
Silvereye - 18 (10)
Singing Honeyeater - (1)
Striated Pardalote - 9
Western Gerygone - (1)
Total - 39 (12) =51

Birds were not particularly numerous this weekend (not unusual for the time of year) however we did have a particularly diverse catch this time. 19 birds of an amazing 12 species were processed, highlights being an Australian Magpie, Australian Raven and Magpie-lark which all came from the same net.
Silvereyes were few and far between but we caught a variety of honeyeaters, which have been notable in their absence recently.
