Overview
What is Eurasian jay
The Eurasian jay (Garrulus glandarius) is a medium-sized crow-family bird (Corvidae) confirmed in Georgia as a year-round resident. The 2024 annotated checklist of the birds of Georgia codes it YR-R: a breeder present throughout the year. Seasonality is classed as high-quality (code A). Occurrence quality is high (H), with photographic evidence. The usual Georgian name is ჩხიკვი; ჯაფარა is also used. Adults are about 32–35 cm long at species level, with a pinkish-brown body, black moustache, white rump, and a bright blue black-barred wing panel. The Caucasus form has a largely black crown. It is not a threat to people. IUCN lists the species as Least Concern. The 2024 checklist assigns the same category nationally.

Identification
How to identify Eurasian jay
A pinkish-brown woodland corvid with a black moustache, white rump, and a bright blue black-barred wing panel. In Georgia the Caucasus form usually shows a largely black crown. Magpies and crows lack that blue wing panel.
- 01
Length about 32–35 cm and wingspan about 52–58 cm at species level; mass is often about 140–190 g in handbook ranges. Body plumage is warm pinkish- brown to rufous-grey. The throat is pale with a bold black moustache stripe. The rump is white and conspicuous in flight. The outer wing shows a striking blue panel finely barred with black — the most reliable field mark at any distance.
- 02
Georgian birds belong to the black-capped atricapillus group. NPLG names the form in the country as Caucasian jay, G. g. krynicki (Kaleniczenko, 1839), distinguished by a largely black crown (not the pale, black- streaked crown of many north-west European birds). Sexes are alike in the field. Juveniles are duller, with a less neat crown pattern, but still show the blue wing panel.
- 03
Eurasian magpie (Pica pica) is also a year-round resident in Georgia on the 2024 checklist: black-and-white with a long graduated tail, without a blue barred wing panel; this atlas has a page for that species. Northern raven (Corvus corax) is a much larger all-dark corvid; this atlas has a page for that species too. Rook, hooded crow, and jackdaw are larger or greyer/blacker corvids without the jay’s pink-brown body and blue wing patch. Northern nutcracker is irregular/scarce (Cas; WV on the checklist) and is heavily spotted white on brown. Alpine and red-billed choughs are mountain birds with red or yellow bills. This atlas does not yet have separate pages for rook, crow, jackdaw, nutcracker, or choughs.
- 04
It is not a threat to people. Leave it alone. A pinkish woodland bird with a harsh screech and a flash of blue on the wing in Georgian parks or oak forest is this species.
Biology
Habitat, diet, behavior, and conservation
Habitat and range
This page does not colour a municipality-by-municipality map. The 2024 checklist confirms country-level resident status but does not publish a regional gazetteer. Do not assume it occurs evenly across Georgia, including treeless high plateaus. NPLG treats it as a resident throughout Georgia, with only minor local wandering. Named locality: the Agency of Protected Areas lists ჩხიკვი among birds of Algeti National Park (Algeti gorge). A Commons photograph from 26 May 2024 documents the species in Tbilisi. Species-level habitat is deciduous and mixed woodland, especially with oaks, plus forest edge, parks, large gardens, and wooded suburbs. Closed treeless steppe and alpine grassland above the tree line are not typical. A separate national elevation band for Georgia is not published here.
Diet
There is no separate Georgian diet study on this page. Across the range the diet is mixed: acorns and other large seeds, nuts, fruits and berries, insects and other invertebrates, and occasionally eggs, nestlings, or small vertebrates. In autumn it caches acorns in soil and leaf litter and retrieves many of them later; unrecovered caches help oaks regenerate. That scatter- hoarding role is documented at species level and is biologically relevant wherever oaks and jays co-occur; it is not a measured Georgian food study.
Behavior
It is active by day. The usual call is a loud, harsh screech; birds also chatter and are well known for mimicking other sounds, including buzzard-like mews. Flight is often short and undulating between trees; the white rump and blue wing panel show clearly then. Nesting is in a tree or tall shrub. Species- level clutches are commonly about four to seven eggs; those figures are from the wider range, not a Georgian nest sample on this page. The 2024 checklist treats the species as a breeder in Georgia. It is resident rather than a long-distance migrant; NPLG notes only slight wandering within the country.
Conservation
BirdLife International assesses Garrulus glandarius as Least Concern on the IUCN Red List. The 2024 Georgian bird checklist assigns global and national Red List category LC. A Georgia-specific population trend is not quantified on this page. Do not catch or keep wild birds. Loss of mature oak woodland and persecution of corvids would be biologically relevant pressures at species level; local threat ranking for Georgia is not published here.
Questions
Frequently asked questions
Short answers to the most important questions about Eurasian jay.
Yes. The 2024 annotated checklist of the birds of Georgia lists it as a confirmed year-round resident (YR-R): a breeder present throughout the year.
In deciduous and mixed woodland, forest edge, parks, and wooded towns. Named sources place it in Algeti National Park and document a May 2024 photograph in Tbilisi. NPLG describes it as a resident across the country. This page does not map every region.
Pinkish-brown body, black moustache, white rump, and a bright blue black- barred wing panel. In Georgia the crown is usually largely black (Caucasian form). Magpies and crows lack that blue panel.
About 32–35 cm long at species level, with a wingspan of about 52–58 cm. Handbook mass is often about 140–190 g. A separate measured series from Georgia is not given on this page.
Acorns and other seeds, fruits, insects, and occasionally small vertebrates or nest contents. It caches acorns in autumn. Diet has not been studied separately in Georgia on this page.
All year, according to the 2024 checklist. It is not treated there as a passage migrant or winter-only visitor.
Yes. YR-R on the 2024 checklist means resident breeder.
It is harmless. It is globally Least Concern and is coded LC nationally on the 2024 checklist. Do not catch wild birds.
