Marked Birds Database update – automation, basic features, new ringing projects and design tweaks

I have been able to do a lot of work since I have last reported on the state of the Marked Birds Database so it is time to give another quick overview of what is new or changed.


My main aim is to let the database do the work as much as possible, wherever possible. Some important new features have now been fully automated.

Current bird age

One of the main hurdles to overcome was the whole concept of the ‘current age’ of a bird and especially when and where it should be added.

I’m happy to say that calculating this age is now fully automated. See a demo in this video:

Current Marker Code

Another concept of the database is that of the ‘Current Marker Code’. It represents the rings that the bird is currently fitted with and it is quite important because it is used to find a bird once it has been added.

Several notation methods exist for this code and some of them can be set as a preference.


Generating this code is now also fully automated, as can be seen in the following videos:

Basic features

Some basic features also still needed to be adressed, including those related to locations.


I have added a full list of all countries of the world, including their flags. The flags make it easy to see where a bird was observed or ringed.


Provinces & states and their codes

A feature that has always been missing was the option to store the name of a province or state and its code.

Even though only two fields needed to be added, automating the processes around it made it a lengthy process to implement.

New ringing projects

The long awaited implementation of wader-type projects still needs to be done but I have come halfway by adding 2 Dutch Oystercatcher projects: one for a project that uses 2 coded rings and one for a project that uses banded rings.



One of the nice features is that you can add all rings simply by entering the short notation code. See this demonstrated in these videos:

Design tweaks

Changes to the design are constantly happening, but the layout with the biggest improvement is the Observation Details layout. By grouping together the fields that are related it is now much easier to ‘read’.


More to come

There is still much work to be done and hopefully I can complete more tasks over the coming months, but the breeding season is approaching so I will be spending lots of time out in the field.

To be continued!
