[Lories. Parrots. Macaws]

Agapornis Selby

Agapornis cana (Gmelin) [Madagascar Lovebird. Grey-headed Lovebird]

    x      Agapornis roseicollis (Vieillot) [Peach-faced Lovebird]

                The hybrids are said to be fertile.
                Legendre, M. 1936.

    x      Melopsittacus undulatus (Shaw) [Budgerigar]

            "Male" Madagascar Lovebird x "female" Budgerigar.  There are a few records
            of alleged hybridization, but the reliability of such reports is questioned both by
            Cayley and by Prestwich.  Page has reported a hybrid that lived to leave the nest.

            Braune,  -. Cayley, N. W. 1938; Gefiederte Weldt, Die 1890; Hokinson, E. 1926,
            1941; Neunzig, K. 1921; Page, W. T. 1918a; Prestwich, A. A. 1943a
 
  Agapornis fischeri Reichenow [Fischer's Lovebird]

    x      Agapornis roseicollis (Vieillot) [Peach-faced Lovebird]

                The two species cross readily.  Reciprocal hybrids have been reported.  According
                to Legendre, the hybrids are fertile.  Prestwich (1950) has given a brief description
                of 3 young hybrids reared in France

                Delacour, J. 1930, 1931; Hampe, H. 1939; Hopkinson, E. 1930, 1931a, 1933a, 1941;
                Legendre, M. 1936; Olivaux, M. C. 1929; Prestwich A. A. 1929, 1950
 
Agapornis lilianae Shelley [Nyasa Lovebird]

    x      Agapornis roseicollis (Vieillot) [Peach-faced Lovebird]

              The cross has occurred in both directions.  The hybrids are fertile. Hopkinson has
              recorded several backcrosses produced by a hybrid "female" mated to a Nyasa "male"
               . A markedly quarrlesome "male" hybrid described by Warren was a little smaller than
               the mother (roseicollis) but larger than the sire.  The incubation period was about 18 days.
 
 
Agapornis nigrigenis W. L. Sclater [Black-cheeked Lovebird]

    x      Agapornis roseicollis (Vieillot) [Peach-faced Lovebird]

                The two species are said to interbreed readily.  According to Marriner, the hybrids are
                fertile inter se.

                Delacour, J. 1930; Hampe, H. 1939; Hopkinson, E. 1926, 1933a, 1941; Legendre, M. 1936;
                Marriner, J. S. 1927; Prestwich, A. A. 1928

    x      Melopsittacus undulatus (Shaw) [Budgerigar]

            "Male" black-cheeked lovebird x "female" Budgerigar.  There is a report in Bird Notes,
            1911, of 4 hybrids which hatched and were said to be doing well.  The authenticity of the
            report has been questioned by Cayley,  Hopkinson (1941) and Prestwich

            Bird Notes 1911d; Cayley, N. W. 1938; Hopkinson, E, 1926, 1941; Prestwich, A. A. 1943a
 
Agapornis personata Reichenow [Masked Lovebird]

    x      Agapornis roseicollis (Vieillot) [Peach-faced Lovebird]

                The cross has occurred in both directions.  The hybrids are said to be fertile.

                "male" masked x "female" Peach-faced Lovebird.  A "male" hybrid described by Hill
                tended to resemble roseicollis in size and coloration.

                Ara, L. A. 1952b; Delacour, J. 1930; Hampe, H. 1939; Hill, W. C. O. 1942; Hopkinson, E. 1931a
                1933a, 1941; Kelly, A. L. 1949; Legendre, M. 1936; Prestwich, A. A., 1949c

    x      Melopsittacus undulatus (Shaw) [Budgerigar]

            Presumed hybrids have been reported.  They appeared to be sterile

            Gjessing, G. A. 1953.
 
Agapornis pullaria (Linnaeus) [Red-headed Lovebird. Red-faced Lovebird]

    x      Agapornis roseicollis (Vieillot) [Peach-faced Lovebird]

                The hybrids are said to be fertile.
                Legendre, M. 1936.

    x      Melopsittacus undulatus (Shaw) [Budgerigar]

            Boosey and Prestwich both doubt the authenticity of this reputed cross.

            Boosey, E. 1952, Prestwich, A. A. 1943a.
