Because that page is a gallery of just one sighting each of all the different birds we are looking out for, while the collection "Gang-gang movement study - sightings of identifiable birds" - has all the sightings. Baldy last recorded in the area in Jan 2023 - Tony is this the first time you have seen Baldy this winter?
Yes, I saw Baldy and partner in late Jan and he disappeared for six months turning up again in late June. I have seen the pair a few times since. They move separately from the main Cook flock of up to about 15 birds.
