Obviously you don't know Common DPs very well then. They are dark grey above, white below (not at all light grey) with a Grey underwing, which has sometimes mostly white, but usually motley coverts. They also have blue feet. Obviously this is not a CDP. The wings are bent, so not a good indication of wingspan. It is small, perhaps an early juvenile, I have found small juveniles every so often and they can be tiny sometimes. Kevin  Bartram

Really? HANZAB and field guide drawings match colour (or shade) for Common Diving Petrel as dark grey above and pale grey below. Not “black & white”, although at sea I guess they could look black & white. I have only ever seen Common Diving Petrel on one day and not recently but they are not that much different in colour above & below as is this bird, although rather more pale than this photo shows. I have like most of us, seen hundreds of dead Short-tailed Shearwaters and thousands of live ones.  The shape looks wrong to me for a Short-tailed Shearwater (wings not narrow enough) and why would someone ask about Short-tailed Shearwater? Surely they are found dead in large numbers. Using HANZAB: Weight of Short-tailed Shearwater given as 480 to 800 grams and Common Diving Petrel given as 110 to 150 grams. Weight of this specimen given as 77 g. I suggest that being underweight is consistent with being dead, but not by that much to match a recently dead shearwater. HANZAB: Wing span of Short-tailed Shearwater given as 95 to 100 cm and Common Diving Petrel given as 33 to 38 cm. Look at the (hopefully) 30 cm ruler, if this is a shearwater, the wing span should be equal to about 3, 30 cm rulers. The wing span of this specimen is mid 30 to 40 cm, nowhere near big enough to match the shearwater.

On evening 5/2/2019 I picked up a small seabird dead less than 24 hours but beginning to smell.

Rubicon Estuary beach, Hawley Beach , just 10 km east of Devonport NW Tasmania .

 Weight 77g , damp but no fat at all,

Wing length 160 mm and tail 60 mm bill length 27 m , skull may have been bit squashed .



I have no idea so any suggestions gratefully received 

Geoff Shannon
