noisy miners

["martin butterfield" <>]

We are currently in GBS week 34.  The earliest GBS DY record for Noisy Miner is week 37 in year 25.  There are several records of DY from week 40 (beginning 2 October) onwards.  Thus the answer to Coral's question is "yes" subject to the qualification below.

In years 24 - 25 of the GBS there have been reports of earlier breeding for this species than in years 7 (the first in which breeding was reported) to 23.  Of interest is:

• one of the sites reporting an earlier breeding evet in year 24 also reported breeding for this species in 6 of the years between 13 and 23 inclusive; but
• the earlier year reports for the site were of DY while the year 24  report commenced with NB and ended with NY in week 44 (still making DY now, rather early).
  

Before getting too excited about this, it should be noted that there are only 21 records (a record in this context is a site reporting at least one breeding observation for the species in a year) in the database.  6 of the records occur in years 24 - 26.

Noisy miners with dependent young (begging fledgling) at Casey Saturday 23 August. Is this early? The GBS data says Nesting activities are reported from early October, with most observations of dependent young being in January.
