- [Nathan] You can see the bill of the chicks starting to poke out.
This bird is gonna hatch tomorrow morning.
- [Speaker] Nathan marks the location of the nest so his team can return tomorrow.
- If we're not there when the chick actually hatches, we're never likely to see them because they are moving away from the nest within a couple of hours of hatching, and it's incredibly difficult to find them in the bog after they've actually left the nest.
- [Speaker] And scientists aren't the only ones searching for nests.
Hidden cameras reveal a variety of predators.
- [Nathan] Uh oh, that's not good.
I found an egg with some, like an open egg with some blood in it.
That looks to me more like it was eaten, than like it hatched.
Got another one?
- [Scientist] Yeah.
- All right, well, let's leave these parents to their anguish.
Yeah.
Not good.
You're rooting for the birds.
That's why we're here.
I mean, it is a part of the whole process, but as, yeah, when you've watched the nest for a long time and it's not a good ending.
- [Speaker] Summer is here.
And from those hollows in the scrub, emerges life.
