Show: Penguins Log of DAT #10 Engineer: Williams Date: Feb 15, 2003 00:00 -8:19 Distant penguins and wind in shrub 8:40 talking -no good -asking about seeing them fight 9:00 9:47 wind, and penguins in distance 9:48 walking 10:01 CJ -what d'we got? DB -well, we have a juvenile and you can see that it just probably died this morning bc you see the eyes are really clear? And this is one of those examples about how any animal has a really hard time going from feast to famine. So this bird -let's just see how heavy it is - I think - 10:23 CJ -so you are using a strain gage... 10:26 DB - ...yup! scale here - So this juv weighs 5 ½ -- 4 ½ kilos -like close to 10 poudns. That is healthy. There is nothing wrong with this bird, except that it is dead -in terms of its weight. So I guess this is what happens sometime to people -where they gain a whole bunch of weight, and then they start fasting, and they loose weight really rapidly bc they quit eating and it could be dangerous to their health -well, some of these juvi every year we find that as these juv go throught the molt, a few of them die and presumably it is a shock to their system -they have been just gorging themselves and they have been a gluton for several weeks and have almost doubled their weight and then they come a shore and have to change all of their body rhythms and their hormones and go through this molt -grow all of these new feathers and loose all of these old feather and some of them die. Occasionally we will see adults that will die during the molt too -but more often its juv. And you can tell that this juv at least had some idication that was healthy and doing well -see these black feathers here? It actually molted some of their chick feathers and grown some new black feathers in here. 11:47. CJ - So he was in the process of molting when he died? 11:48 DB - Well, he was just getting ready. If you feel -he is just barely starting the flippers are just starting to get slightly swollen, but he is not even in the first stage which we call slightly swollen. The next stage is we call feathers erect. He is just started to get slightly swollen. But the feathers -when he is feathers erect -when we go like this they will stay up the whole time (you can hear faint finger rubbing against feathers) they are still coming down a little bit. Then after that they are still loosing these feathers. CJ -uh huh. DB -and then they will molt a corner and then half and then all of them -and he will grow his new feathers, but it will take him about 3 weeks to do that -and during that 3 weeks he doesn't eat a thing. He can drink water but that is it. So that is one of the risks that people we know have. You know, if they are eating a lot and then they just suddenly quit -it is such a shock to the system, and presumably you know it is the same thing happening to these penguins. 12:43 12:49 DB -anyway -I would like to kind of know 12:50 AMBI - her getting out the equipment to measure the bird 12:58 CJ -what are you measuring? 12:59 DB- I am measuring the bill ...
