OBSERVATIONS: |

09-04-2023 |
adult: |
2 unringed cach present at blocks on N side, in front of location. Search for nest today. |
26-04-2023 |
nest: |
same location, old codes still present. Refreshed with spray. |
|
eggs: |
1x egg, egg is cold. Nest abandoned? Egg measured. |
|
comment: |
This used to be an early nest, 3 eggs should be floating already this date. In retrospect: late, as one parent is now Herring Gull? |

adult: |
partner 1 = cach adult. |
18-05-2023 |
nest: |
3 eggs. |
27-05-2023 |
pulli: |
3x chicks ringed and measured. |
18-06-2023 |
pulli: |
3x chicks present, but not in category 'fledged', still too young. |
|
pullus: |
g-8|S with terrible head wound, therefore not measured. Will probably not survive. |
|
pullus: |
g-8|T between blocks, was checked upon by adult Herring Gull, close to nest site. Hence: at least one parent is Herring!? |

pullus: |
g-8|U caught and measured. |
