Unfortunately, it appears that the season is over for Havoc and Ava. 
 
During last week's monitoring Ava was sitting tight on her second egg, although it was unlikely to be successful.  The eggs will hatch in the same order they are laid, but with only two eggs, it should only be matter of days after the first egg hatches before we would expect the second chick to emerge.  Finally Ava gave us a glimpse, but then it was of a listless chick.  It didn't look promising.
 
This week Ava is sitting on the bunker ledge, preening in the warmth of the afternoon sun and checking out the adjacent ledge (and checking out me!).  There was no sign of the chick or the second egg.  Today the bunker ledge is empty

The rain has been bucketing down and Ava is snuggled in tight against the vertical of the bunker ledge.  Is that a piece of egg shell I spy? Back for a second look and Ava seems to be sitting amongst the leftovers of lunch? The rain has eased ... Ava moves along the ledge to prepare an afternoon snack .... who is this that appears from behind the vertical?

For Peregrine Falcons, the incubation period is 33 to 35 days from the date the last egg was laid.  How long the eggs had been on the bunker before they were discovered in mid September is uncertain. If we were attentive and found the eggs soon after they were laid, 28 days have past today and we're only days away from finding out if the nest has been successful this year.  Cross your fingers!

This image (apologies for it's poor quality) shows the two eggs sitting in the makings of a scrape on the coal bunker.  Nice work Ava.  It looks like the eggs are sitting tight, no longer rolling the length of the beam.  Only time will tell if the effort enables the eggs to be successfully incubated and hatch.

A quick check through the peep hole and the heart sank as there was no sight of Ava on the ledge.  Thought Ava would be sitting below proud as punch in her newly formed scrape.  However down went the extension pole and the camera monitor reveals ... Ava sitting midway along the beam. Phew! The camera vision isn't great so it's difficult to distinguish a scrape, but hopefully Ava has moved the substrate around to give her eggs a buffer against the metal beam. Off momentarily to receive a breakfast delivery from Havoc, Ava reveals two eggs.

As far as nest sites on the Power Station go, Ava's favourite bunker ledge has a few things going for it: it's protected for the southerly wind and weather; it's not adjacent to temperatures in excess of 500°C (that's over 900°F!); there is little vibration; and no passing foot traffic. Not working for it is the lack of substrate leaving the eggs exposed to the cold metal and free to roll back and forth along the beam.  The solution - add substrate! 
 
Such an easy solution one would think, except when your only access to the ledge is a 50mm hole in a 15cm thick concrete slab located 4 metres above (and slightly to the right) of the ledge.  However with some ingenuity, 40mm conduit and clever camera work ... ta da! substrate! Let's hope Ava can make herself a splendid scrape out of the material we're provided.

We have an egg!  Actually, we have two!!  The eggs are rarely left uncovered during incubation but Ava kindly gave us a sneak peek while she stretched her legs (and wings).

Welcome back! The 2013 Peregrine falcon breeding season at Alcoa Anglesea is underway.
 
The nest box for Havoc and Ava remains vacant.  Instead Ava has elected to return to the coal bunker ledge of the previous nesting attempts of 2010 and 2011.
