It appears to be the mean function operating on the coarsen object xarray/tests/test_dataset.py#l.5676. The Rolling class uses _reduce_method() to check if the calling function is present in duck_array_ops, presumably to enable extensibility in line with NEP22.

FWIW the dataset object returned by that call in the test looks like this: values = array([[10. , 10.05050505, 10.1010101 , 10.15151515, 10.2020202 ], [10.25252525, 10.3030303 , 10.3535353...96 , 14.64646465, 14.6969697 , 14.74747475], [14.7979798 , 14.84848485, 14.8989899 , 14.94949495, 15. ]]) axis = (1,), skipna = None, kwargs = {'keep_attrs': True}, func = <function nanmean at 0x7f044d715268>, nanname = 'nanmean' ```
