- At least some green present, but may be dark brown
to light green, pale gray or yellow.
- May be very pale when calling
- Become darker when upset or sick
- A larger, stouter treefrog
- Profuse, round, dark markings usually persist thru
various color changes
- Large toe pads present
- Sexual Dimorphism:

- Natural History:

levels, even the ground.
- May burrow, particularily in hot dry weather.
- It feeds on various insects.
- Breeding occurs from March to August.

- Breeds in shallow pools or ponds. Individuals may
call in shallow temporary pools after rain, but most groups are in

- Females deposit eggs singly on the bottom
- Total egg production/female about 2000
- Voice: Sonogram
(Long, Wheeler, Oglethorpe, & Columbia Counties) Cope's Gray Treefrogs
& Fowler's Toads
- A barking call of nine or ten raucous syllables is
uttered from high in the treetops or as moving down to breeding sites
- The breeding call, given close to the water, is a
single explosive Doonk or Toonk often repeated at intervals of one to
- Tadpole stage: 40 - 70 days
- Transformed size: 14 - 20 mm
- LTRF 2/3; narrow midventral gap in marginal papillae
absent; eyes lateral; P-3 medium to short, P-2/P-3 > 1.2; east
of Mississippi River
- lower jaw sheath robust and very wide, half nearest
serrated edge very black, remainder brown; P-2/P-3 ca. 1.5; length of
one side of A-2/width of medial gap ca. 4.6; midventral marginal
papillae biserial; fins clear until tadpole gets quite large, then has
punctate melanophores proximally and stellate ones distally, the latter
often dilate at night to produce jet-black tail, a white line caused by
lack of pigment in subintegumentary layers extends from each naris
toward the adjacent eye, tail muscle lightly pigmented until tadpoles
get large; throat not pigmented
- In North America, North Carolina to south Florida and
eastern Louisiana, chiefly in the coastal plain but also in many upland
- Isolated colonies in Deleware and adjacent Maryland,
southwest Kentucky and adjacent Tennesee and in southeast Virginia
