Number of the nesting species' eggs counted in the nest.
Number and status of live young of the nesting species counted in the nest.
Number of dead young of the nesting species found in the nest.
Estimated hatch dates (EHD).
Actual date and number of young hatched.
The number of unhatched eggs.
Estimated fledge dates (EFD).
Actual date and number of young fledged.

Cornell Codes to be used in the observation record

NO = no adults seen or heard
VA = adult(s) remained in vicinity of the nest box during the check
BA = adult building nest or carrying nest material
AA = adult flushed from nest during check
RA = adult remained on the nest, or in the nest box
FA = adult feeding young at nest or seen carrying food
DA = dead adult(s) at or near nest site

NO = no nest
IN = nesting materials present; nest building appears to be underway
CN = nest appears to be structurally complete, with an obvious central cup
DN = damaged nest
AN = another nest found in same site (begin new attempt)
NN = non-avian nest found (bees, mouse, squirrel--describe in comments)
FN = flattened nest, with fecal matter
RN = nest removed, remover unknown

NO = no young present in nest
HY = at least one chick hatching or has just emerged from egg
NY = nestlings naked and pink, or with sparse down, eyes typically closed
PY = wing feathers emerging, eyes open
FY = body feathers completely cover skin
VY = vocal young, heard only

NO = no management activities conducted
BM = banded adults or young at nest (only to be done by a permitted individual)
EM = unhatched host eggs removed
NM = nest box management (cleaning, plugging, unplugging, replacing boxes; removing old nesting material, etc.)
